1 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
4 SCM_ROCHARS instead of SCM_CHARS.
6 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
7 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
9 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
11 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
12 This is quite important since the latter clears the
13 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
14 every single character read...
16 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
18 * print.c (scm_iprin1): Removed suspect looking (and indeed
19 malevolent) semicolon after test for user supplied closure print
20 procedure. (Thanks to Telford Tendys.)
22 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
23 (scm_memq, scm_memv, scm_member): Do argument checking *before*
24 starting to search the list. Removed call to sloppy_mem_check.
26 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
27 procedures: Same as scm_delq_x et al, but delete maximally one
30 * options.c (scm_options, scm_init_options): GC-protect option
31 values of type SCM. (Thanks to Telford Tendys.)
33 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
35 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
36 make sure that there always is a "real" scm_lookupcar.
38 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
40 * read.c, read.h (history-length, history-file): New read options.
41 (scm_read_options): Stifle history to history length.
43 * readline.c (read-history, write-history): New procedures.
45 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
47 * eval.h (scm_macro_eval_x): Removed declaration.
49 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
50 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
51 Renamed and made global.
53 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
54 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
56 * evalext.c, evalext.h: New files. Contain non-R5RS things
57 having to do with evaluation.
59 * evalext.c (serial-map): New procedure: Version of `map' which
60 guarantees that the procedure is applied to the lists in serial
62 (sequence->list): New syntax: Version of `begin' which returns a
63 list of the results of the body forms instead of the result of the
65 (scm_definedp, scm_m_undefine): Moved from eval.c
67 * evalext.h (scm_m_sequence_to_list): Added declaration.
69 * macros.c, macros.h: New files.
70 (procedure->syntax, procedure->macro, procedure->memoizing-macro,
71 macro?, macro-type, macro-name, macro-transformer): Moved from
73 (scm_make_synt): Moved from eval.c
75 * procs.c, procs.h (procedure-documentation): Moved from eval.c.
77 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
80 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
82 * debug.c, print.c: Added #include "macros.h".
84 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
86 This change adds the ability to use `unread-char' multiple times
87 without interspersed reads and adds the new procedure
88 `unread-string'. The change is optimized for the common case of
89 unreading a single character. This is also the reason behind the
90 choice to store characters in the port itself: in most cases no
91 extra malloc is required.
93 The amount of code in some macros in ports.h has been increased to
94 the extent that they would fit better as C functions, but, since
95 this code belongs to the port representation, such functions
96 should be placed in ports.c which would cause calls back and forth
97 between ports.c and genio.c. That is not good for performance.
98 Also, keeping them as macros allows the compiler to do some
99 optimizations which are needed to make the current interface
100 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
102 One benchmark (Guile startup time) indicates an increase of
103 loading speed of 1%. Another (reading (using `read') boot-9.scm
104 10 times) shows no change in performance.
106 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
107 made to find a beautiful solution.)
109 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
110 (SCM_TRY_CLRDY): New macro: Only clear the first unread
111 character. (SCM_CLRDY clears all.)
112 (SCM_N_READY_CHARS): New macro: Returns number of unread
113 characters in a port. Returns wrong answer if SCM_CRDYP is false.
114 (struct scm_port_table): New fields: `entry' contains port table
115 index, `cp' points to last unread char, `cbuf' is the buffer for
116 unread chars, `cbufend' points after end of the character buffer.
118 * ports.h, ports.c (scm_unread_string): New procedure.
119 (scm_grow_port_cbuf): New function.
121 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
123 (scm_generic_fgets), fports.c (local_fgets): Use a loop
124 to read unread characters. Use SCM_TRY_CLRDY instead of
127 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
129 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
131 * genio.c, genio.h (scm_ungets): New function.
133 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
136 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
138 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
139 declarations. (Thanks to Russ McManus.)
141 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
143 * numbers.c (num2long): As a software archeologist, I'm proud of
144 this finding! :) Preliminary dating suggests an almost 4 year old
145 remnant from the SCM ancestor. The sample has been removed from
146 the finding site and is now safely stored in the repository.
148 * numbers.h: Removed prototype for num2long.
150 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
152 * gh_data.c (gh_scm2doubles): Make it possible to pass result
154 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
155 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
156 * gh.h: Updated and added prototypes.
158 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
160 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
162 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
164 * guile-snarf.in: Never generate an empty file. (Thanks to
167 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
168 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
169 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
170 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
171 gh_new_procedure5_0): Specify argument types, to appease C++
172 compilers. (Thanks to Brad Bowman.)
174 Bug reports from Russ McManus:
175 * guile-snarf.in: If the CPP environment variable is set, use that
176 as the C preprocessor, instead of the preprocessor autoconf
178 * snarf.h (SCM_PROC): Cast the function pointer passed to
179 scm_make_gsubr, to satisfy C++.
181 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
182 Use the handler passed, instead of ignoring it and using
183 gh_standard_handler. (Thanks to Etienne Bernard.)
185 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
187 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

210 * script.c (scm_compile_shell_switches): Define
211 use-emacs-interface in the root module, so the repl code can see
212 it. See today's change to top-repl in ice-9/boot-9.scm.
214 * filesys.c (set_element, get_element): Make sure that `element'
215 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
216 Boekemeier and Jorgen "forcer" Schaefer.)
218 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
220 * chars.c (scm_charnames): In ASCII character name table, make
221 newlines print as #\newline by default, not #\nl.
223 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
224 alphabetical order. Oh thrills. But it helps me know how far
225 along in the compilation I am.
226 * Makefile.in: Regenerated.
228 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
230 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
231 #bytes(...) to #y(...), and syntax for short vectors from
232 #short(...) to #h(...). This may seem nutty, but, like the other
233 uniform vectors, byte vectors and short vectors want to have the
234 same print and read syntax (and, more basic, want to have read
235 syntax!). Changing the read syntax to use multiple characters
236 after the hash sign breaks with the conventions used in R5RS and
237 the conventions used for the other uniform vectors. It also
238 introduces complexity in the current reader, both on the C and
239 Scheme levels. (The Right solution is probably to change the
240 syntax and prototypes for uniform vectors entirely.)
242 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
244 Don't use local_fgets on sockets; ftell doesn't work on sockets.
245 (Thanks to Jorgen "forcer" Schaefer.)
246 * ports.h (SCM_NOFTELL): New flag.
247 * fports.c (local_fgets): If it's set, use the generic fgets.
248 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
250 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
252 * script.c (scm_compile_shell_switches): Add handling of -q switch
253 (inhibit loading of user init file).
254 (scm_shell_usage): Add usage text for -q switch.
255 (scm_compile_shell_switches): Always load user init file first if
258 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
260 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
261 and is now broken under NetBSD. I can't fathom what it's trying
262 to do, so I've replaced it with something that I do understand,
263 which seems to work, and which isn't broken on NetBSD. "Progress?
264 You Decide." (Thanks to Perry Metzger.)
266 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
267 signed/unsigned comparison.
269 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
271 Warning fixes from Greg Harvey:
272 * unif.c (scm_array_set_x): initializer for pos
273 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
274 * struct.c (scm_struct_ref, scm_struct_set_x): Added
275 initializers for field_type, since EGCS so desparately wants to
277 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
278 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
279 when GUILE_DEBUG is defined.
280 * dynwind.h (scm_wind_chain): Same.
281 * ports.h (scm_pt_size, scm_pt_member): Same.
282 * print.h (scm_current_pstate): Same.
283 * procs.h (scm_make_cclo): Same.
285 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
287 Handle short and long long uniform arrays properly. (Thanks to
289 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
290 raeql_1): Add cases for scm_tc7_svect (short vectors) and
291 scm_tc7_llvect (long long vectors).
293 Change the way libguile and boot-9.scm are timestamped, to try to
294 get rid of these spurious mismatch warnings. Now both
295 libguile/versiondat.h and ice-9/version.scm are generated directly
296 by the configuration process, rather than having version.scm
297 generated directly, and libguile/versiondat.h generated by the
298 Makefile, which is generated by configure. It seems that
299 sometimes the Makefile would change, but versiondat.h depends on
300 Makefile.in, not Makefile, so it wouldn't get rebuilt.
301 * Makefile.am (versiondat.h): Target removed; this is generated
302 directly by the configure script now.
303 (BUILT_SOURCES): Remove versiondat.h.
304 * versiondat.h.in: New file, transformed by the configure script
306 * Makefile.in: Regenerated.
308 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
309 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
310 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
311 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
312 if we want to use them in a header file some day, we can. (Thanks
315 * stime.c (scm_get_internal_real_time): Do the arithmetic using
316 SCM numbers, so we won't have rollover problems; the range of a
317 signed long in milliseconds is about 25 days. (Thanks to Karl
320 Don't redefine sleep and usleep; fix this problem now.
321 * coop.c (sleep, usleep): Remove declarations; we don't use or
322 redefine these any more.
323 (scm_thread_usleep, scm_thread_sleep): New functions which do the
324 job of usleep and sleep in a thread-friendly way. We can use
325 these in the rest of Guile. Define versions for systems both with
327 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
328 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
329 we're just using it, not redefining it, we can use a K&R style
331 (sleep): Declare this, too, if the system hasn't.
332 (scm_sleep, scm_usleep): Use scm_thread_sleep and
333 scm_uthread_sleep if they're available; otherwise, just call the
335 * scmconfig.h.in: Regenerated.
337 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
339 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
341 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
343 * threads.c: Doc fix.
345 The argument type of usleep varies from system to system,
346 as does the return type. We really shouldn't be redefining usleep
347 at all, but I don't have time to clean that up before the 1.3.
348 release. It's on the schedule for afterwards. (Thanks to Julian
350 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
352 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
353 * scmconfig.h: Regenerated.
355 * simpos.c (scm_software_type): Procedure deleted. This isn't the
356 right way to handle system variation. Autoconf's approach is the
358 * simpos.h (scm_software_type): Declaration deleted.
360 * script.c (scm_find_executable): Don't test if unix is #defined
361 here; first, NetBSD doesn't #define it, and second, it's the wrong
362 way to go about these things. (Thanks to Perry Metzger.)
363 (dld_find_executable): Delete this MSDOS support code. This isn't
364 the way we want to support this; it needs to be rethunk at a
367 * genio.c (scm_do_read_line): Don't just politely check that the
368 line was either non-empty or EOF. Abort if it's empty and not
371 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
373 * scmconfig.h.in: Regenerated.
375 * libguile.h: Don't omit the dynamic linking functions. (Thanks
378 * genio.c (scm_do_read_line): Count lines correctly when the file
379 doesn't end in a newline.
381 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
383 * genio.c (scm_do_read_line): Maintain the line count correctly.
384 (Thanks to Harvey J. Stein and Greg Harvey.)
386 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
389 * numbers.c (big2str): Protect t from garbage collection until
390 we're done. (Thanks to Gary Houston.)
392 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
394 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
396 * Makefile.in: Regenerated.
398 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
399 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
402 Do magic to mix reads and writes on stdio FILE-based ports.
403 (Thanks to Christian Lynbech.)
404 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
406 (pre_read, pre_write): New functions.
407 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
408 local_fputs): Call them.
409 (local_fflush): Mark the port as ready for reading and writing.
410 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
411 flags on new port objects. This might not be accurate --- who
412 knows what state the FILE * is in when we get it --- but it won't
413 do extraneous calls to fflush or fseek, so it's no worse than the
414 behavior before this change.
415 * ports.h: Add comment.
417 Centralize the creation of port objects based on stdio FILE * in
418 fports.c; don't just throw them together anywhere.
419 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
420 what the rest of Guile wants. Don't set the revealed count;
421 that's only appropriate for stdin, stdout, stderr.
422 (scm_standard_stream_to_port): This function does set the revealed
424 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
425 not scm_stdio_to_port.
426 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
427 * fports.c (scm_open_file): Same.
428 * posix.c (scm_pipe): Same.
429 * socket.c (scm_sock_fd_to_port): Same.
430 * ioext.c (scm_fdopen): Same.
431 (scm_freopen): Moved from here to...
432 * fports.c (scm_freopen): ... here. This is really something that
433 munges the internals of an fport, so it should go here.
434 * fports.h (scm_stdio_to_port): Adjust prototype.
435 (scm_standard_stream_to_port, scm_freopen): New protoypes.
436 * ioext.h (scm_freopen): Prototype removed.
438 * filesys.c (set_element, get_element): This can work on both pipe
439 and file ports, so use SCM_FPORTP to typecheck, instead of testing
442 * scmconfig.h.in: Regenerated.
444 Change the definition of the functions in scm_ptobfuns so that
445 they get passed the port object, not the port's stream.
446 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
447 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
448 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
449 Pass the port itself to the scm_ptobs function.
450 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
451 scm_generic_fgets): Same.
452 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
453 getc_void_port, fgets_void_port, close_void_port): Just change the
454 argument names; these functions don't really do anything.
455 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
456 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
457 port as an argument, and use SCM_STREAM to get the stdio FILE *.
458 Also, use prototyped definitions, and get rid of the extra
460 (scm_fptob, scm_pipob): We don't need casts here any more.
461 * strports.c (prinstpt): Use prototype declarations.
462 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
463 and use SCM_STREAM to get the string info. Also, use prototyped
464 definitions, and get rid of the extra declarations.
465 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
468 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
469 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
471 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
472 scm_fgets, for consistency.
473 (scm_fptop, scm_pipob): References updated.
475 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
477 Include the source location in error messages for scripts.
478 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
479 stack is still there when we catch the error.
480 * throw.c (handler_message): If we are handling an error with a
481 message, then put together the proper arguments and call
482 scm_display_error, instead of scm_display_error_message. That
483 displays source location, if it can find it.
485 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
487 * gc.c (scm_unprotect_object): Change this so that calls to
488 scm_protect_object and scm_unprotect_object nest properly.
489 (scm_protect_object): Doc fixes.
491 * strings.c (scm_string_set_x): Require the argument to be a
492 writable string, not a substring or a symbol.
493 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
494 (Thanks to John Redford and Charbel Jacquin.)
496 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
498 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
500 * eval.c (safe_setjmp): Remove this misunderstanding.
501 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
504 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
506 * libguile.h: Mark these as C declarations, for compilation by C++
509 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
510 __cplusplus clause. I seriously doubt this ever worked the way
511 the author seems to have intended.
513 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
515 Utterly needless cleanups to hopelessly messy code.
516 * ports.c: Doc fixes.
517 (scm_fflush): Moved to ...
518 * genio.c (scm_fflush): ... here, amongst all the other port
519 method invocation functions.
520 * genio.h, ports.h: The prototype moves too.
522 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
524 * backtrace.c (display_error_body): The current frame does not
525 always have a parent frame; consider a function called directly
526 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
529 * alloca.c (alloca): Undo yesterday's changes, and simply call
530 malloc directly for storage, and abort if we don't get what we
531 want. The situation is much simpler --- just call malloc. Emacs
532 has bizarre/evil requirements (signal handlers might malloc unless
533 you set this global flag, so you have to set the flag around all
534 calls to malloc) which we are certainly not going to conform to,
535 so we can do the simple and obvious thing.
537 * coop.c (coop_condition_variable_wait): Make this function
538 static. It's only useful internally --- you should never just
539 wait on a condition variable.
540 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
542 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
544 * unif.c (scm_array_set_x): Accept any kind of number as an
545 element for a uniform vector of doubles. This is more consistent
546 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
548 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
549 works; I can't conveniently test it myself. (Thanks to Dvid
550 Tillman for the bug report.)
554 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
555 from here, not from scm_compile_shell_switches (which is a pretty
556 dumb place to do it).
557 (scm_load_startup_files): New function.
558 (scm_ice_9_already_loaded): Variable moved to here from script.c.
559 * script.c (scm_compile_shell_switches): Don't load the startup
561 (scm_ice_9_already_loaded): Variable moved.
562 * init.c (scm_load_startup_files): Prototype for new function.
563 * gh_init.c (gh_enter): Doc fix.
565 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
567 Some anti-warning changes from Greg Harvey.
568 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
569 warnings when it doesn't understand our NORETURN declarations in
571 * posix.c (scm_mknod): Similar.
573 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
575 * posix.c (scm_getpwuid): If we can't find an entry, return our
576 own message, instead of using scm_syserror --- the getpwMUMBLE
577 functions don't set `errno' to anything interesting.
579 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
581 Get rid of warnings from the cooperative threading system.
582 * threads.h (scm_single_thread_p, scm_yield,
583 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
584 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
585 scm_wait_condition_variable, scm_signal_condition_variable): Add
586 prototypes for these Scheme-visible functions.
587 * coop-defs.h (coop_next_runnable_thread,
588 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
589 Prototypes for these here, even though they're from iselect.c.
590 (coop_condition_variable_wait, coop_join): Add prototypes.
591 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
592 scm_threads_free_condvar): Make these smob functions static.
593 * coop-threads.h (coop_init): Give this a real prototype.
594 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
595 (coop_next_runnable_thread): No need to provide prototype; it's in
598 * scmconfig.h.in: .detarenegeR
600 * iselect.c, threads.c: Doc fixes.
602 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
604 * Makefile.in: Regenerated with a patched automake, to get
605 dependency generation right when using EGCS.
607 * inet_aton.c (inet_aton): Add prototype, to remove compiler
608 warning. (Thanks to Robert Pluim.)
610 * inet_aton.c (inet_aton): Reassure the compiler that the
611 arguments to the <ctype.h> macros are all unsigned characters, not
614 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
616 Getting rid of more warnings...
617 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
618 today's change to ../configure.in.
619 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
620 * scmconfig.h.in: Regenertaded.de.,.__
621 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
622 (scm_localtime, scm_mktime): Use a const char * to manipulate the
625 * readline.c: Doc fix.
626 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
627 * readline.h (scm_filename_completion_function): Add prototype.
628 (scm_init_readline): Make this into a prototype.
630 * readline.c (scm_filename_completion_function): Use SCM_PROC to
631 declare this, instead of calling scm_make_subr manually.
633 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
635 * readline.h (scm_init_readline): Add prototype for this.
636 (scm_init_readline): Make this a real prototype.
638 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
640 Warning fixes from Maciej Stachowiak:
641 * backtrace.h (scm_display_application, scm_backtrace): Add
643 * debug.c (scm_m_start_stack): Make this function static.
644 * fluids.h (scm_fluid_p): Add prototype.
645 * procprop.c (scm_i_procedure_arity): Make this function static.
646 * regex-posix.c (scm_regexp_error_msg): Make this function static.
647 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
648 * root.h (scm_dynamic_root): Add external prototype.
649 * scmsigs.h (scm_usleep): Add external prototype.
650 * script.h (scm_init_script): Use prototype, not K&R decl.
651 * stacks.h (scm_stack_id): Add external prototype.
652 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
654 1998-09-30 Mark Galassi <rosalia@cygnus.com>
656 * gh.h: took out the definitions of vset and vref, since they are
657 replaced by the proper vector routines that correspond to the R4RS
660 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
662 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
663 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
664 third argument, a C expression that should result in a SCM value,
665 which is used to initialize the variable. Reimplemented
666 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
669 * version.h (scm_libguile_config_stamp): Add prototype.
670 (From Maciej Stachowiak.)
672 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
674 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
675 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
677 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
679 * print.c (scm_iprin1): Rather than having one i, and using it in
680 several places, declare a fresh i local to each block where it is
681 used, and give it a signedness appropriate to its use in each case.
684 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
687 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
688 signed/unsigned clashes.
690 * posix.h (scm_tmpnam): Added prototype.
692 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
693 scm_make_subclass_object): Add external prototypes.
695 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
696 comparison is okay here.
698 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
700 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
701 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
703 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
706 * load.c (swap_port): Make this function static.
708 * load.c (scm_search_path): Make max_path_len and max_ext_len
709 unsigned, since they're compared against string sizes.
711 * load.c (init_build_info): Make i unsigned.
713 * ioext.h (scm_read_line): Add prototype.
715 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
716 scm_hash_fn_remove_x): Make hash bucket index local variable k
717 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
718 accurately as possible.
720 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
721 comparisons, and range checking to make sure those casts are
724 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
725 signed/unsigned comparisons.
727 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
728 avoid signed/unsigned comparisons.
729 * smob.h (scm_numsmob): Change extern declaration to match.
731 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
732 avoid signed/unsigned comparisons.
733 * ports.h (scm_numptob): Change extern declaration to match.
734 (scm_current_load_port, scm_set_port_line_x,
735 scm_set_port_column_x): New prototypes.
737 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
738 test code, and it causes warnings.
740 * gh.h (gh_int2scmb, gh_uniform_vector_length,
741 gh_uniform_vector_ref): Added prototypes.
743 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
744 debugging support unconditionally. That's backtrace.c, stack.c,
745 debug.c, and srcprop.c.
746 (EXTRA_libguile_la_SOURCES): Omit those from here.
747 * Makefile.in: Regenerated.
749 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
751 * options.c (scm_options): Bugfix: Allow empty list of options!
753 * debug.c, debug.h (scm_single_step): Removed.
754 (scm_with_traps): New procedure. This procedure could easily be
755 written in Scheme but needs to be highly optimized.
757 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
759 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
760 Check SCM_TRAPS_P before trapping.
762 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
764 Changes to avoid signed/unsigned comparison warnings.
765 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
766 (scm_gc_sweep): Make n and j local to the blocks they're used in,
767 so they can have appropriate types for each application. Make i
768 signed. Use initializers in some spots. I'll probably pay for
770 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
771 (scm_must_realloc): Make nm unsigned.
772 (init_heap_seg): Make new_seg_index and n_new_objects signed.
773 (scm_init_storage): Use prototype-style definition, and make the
775 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
776 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
778 * filesys.c (scm_readlink): Make local vars rv and size ints, to
779 avoid signed/unsigned comparison warnings, and because the return
780 value of readlink may be -1. Don't bother casting the third
781 argument to readlink.
783 * filesys.c (scm_dirname, scm_basename): Move these to their own
784 page, at the end of the file.
785 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
787 * eval.h (scm_eval_options_interface): Add external prototype for this.
788 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
790 * eval.c (scm_lookupcar1): Make this static.
792 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
793 Make these prototype declarations, not K&R-style.
795 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
796 unsigned comparison warning.
798 * appinit.c: File removed. It had a single function in it, empty,
799 whose reason for existence is explained in no documentation or
800 comment. I think it's there as a default for some Tcl-style
801 initialization, but Tcl abandoned that approach a while ago.
802 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
803 (BUILT_SOURCES): Remove appinit.x.
804 * Makefile.in: Regenerated.
806 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
808 * Makefile.in: Regenerated using the last public version of
809 automake, not the hacked Cygnus version.
811 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
813 Remove Totoro kludge.
814 * Makefile.in, scmconfig.h.in: Regenerated.
815 * init.c, readline.c: Don't check if TOTORO is #defined.
817 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
819 * Makefile.am: Adjust for new thread configuration system.
820 (INCLUDES): Include the value of THREAD_CPPFLAGS.
821 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
823 (THREAD_LIBS): Definition deleted; automake will generate such
824 things automatically.
825 * Makefile.in: Regenerated.
827 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
829 Simplify smob and port marking; set the mark bit in the generic
830 marking code, and make marker routines only responsible for
831 turning up outgoing pointers.
832 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
833 before calling the marking function. Don't call the marking
834 function if it's zero.
835 * markers.c (scm_mark0): Just return #f. This function isn't
836 necessary at all now, but it's harmless to call it. We'll leave
837 it in so other folks' code doesn't croak at link time.
838 (scm_markcdr): Don't call SCM_SETGC8MARK.
839 * async.c (mark_async): Don't call SCM_SETGC8MARK.
840 * dynl.c (mark_dynl_obj): Same.
841 * root.c (mark_root): Same.
842 * srcprop.c (marksrcprops): Same.
843 * unif.c (markra): Same.
844 * variable.c (scm_markvar): Same.
845 * ports.c (scm_markstream): Same.
846 (void_port_ptob): Specify zero for our marking function.
847 * debug.c (debugobjsmob): Same.
848 * dynwind.c (guardsmob): Same.
849 * filesys.c (dir_smob): Same.
850 * fluids.c (fluid_smob): Same.
851 * fports.c (scm_fptob, scm_pipob): Same.
852 * mallocs.c (mallocsmob): Same.
853 * regex-posix.c (regex_t_smob): Same.
854 * smob.c (freecell, flob, bigob): Same.
855 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
856 * throw.c (jbsmob, lazy_catch_funs): Same.
858 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
860 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
861 scm_copy_tree on code in order not to let memoized code to leak
862 out. Thus, scm_copy_tree needs to copy vectors as well since
863 quasiquote can introduce evaluated code also inside vector
866 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
868 * eval.c (scm_copy_tree): Removed ability to copy vectors.
870 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
871 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
874 * unif.c: Say that ivect and uvect are of type signed and unsigned
875 long instead of int in commentary so that it correctly describes
878 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
880 * stime.c: Removed declaration of strptime. (It should be
881 declared by the system headers. If it turns out that some systems
882 don't, we'll handle that then.) (Thanks to Greg Troxel.)
884 * stime.h: Renamed TIMEH --> STIMEH
886 * backtrace.c (scm_display_error, scm_display_backtrace): In order
887 to increase portability, don't use structure assignment.
888 (Thanks to Nicolas Neuss.)
890 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
892 (finalize_fd_sets): Added empty statement after last case label.
893 (Thanks to Nicolas Neuss.)
895 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
898 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
900 * init.c, readline.c: OK, I won't have these readline.x bug
901 reports anymore. We've had them since April. The current reason
902 is a completely unintelligible failure of totoro.red-bean.com to
903 do the test for rl_getc_function in libreadline correctly. This
904 kludge overrides the test if we're on totoro so that the snapshot
905 generation process can work.
907 * readline.c: Define a strdup replacement if not existent on system.
909 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
911 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
912 This change makes scm_make_vector R5RS compatible. We cannot keep
913 the third argument since people want to be able to deduce the form
914 of the C function call only by looking at R5RS. (At the same time
915 we have removed some unnecessary complexity!)
917 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
918 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
919 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
920 argument in call to scm_make_vector.
922 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
924 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
925 This macro is useful in applications.
927 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
929 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
930 (scm_parse_path, scm_search_path): New Scheme level procedures.
932 * load.h (scm_internal_parse_path, scm_parse_path,
933 scm_search_path): Declared.
935 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
937 * filesys.c (dirname, basename): New procedures.
939 * init.c (scm_boot_guile_1): Removed condition around
942 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
943 new data type (guards) for representation of C level guards and
944 data on the wind chain.
945 (scm_internal_dynamic_wind): New function.
947 * dynwind.h: Declare scm_internal_dynamic_wind.
949 * root.h (scm_root_state): Added scm_cur_loadp.
951 * root.c (mark_root): Added comment about cur_loadp.
953 * load.c: #include "dynwind.h";
954 (scm_primitive_load): Use scm_inner_dynamic_wind to update
957 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
959 * ports.c (current-load-port): New procedure.
961 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
963 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
964 not a tty, return #f.
966 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
967 to Julian Satchell and Roland Kaufmann.)
969 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
970 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
972 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
974 * debug.h, debug.c (scm_start_stack): New function. Implements
975 the guts of old scm_m_start_stack.
977 * debug.c (scm_m_start_stack): Use scm_start_stack.
979 * init.c (scm_start_stack, scm_restart_stack): Renamed to
980 start_stack and restart_stack. (These have static scope.)
982 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
984 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
985 readline functions to come in release 2.3. (Thanks to Chet
987 (handle_errors): Use the above functions.
989 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
991 * readline.c: Improvements for readline support: Handle errors
992 better; Implement before-read-hook.
994 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
996 * init.c (scm_boot_guile_1), readline.c: Test for
997 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
998 assure that we have version >= 2.1.)
1000 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1002 * readline.c (scm_readline): Defer interrupts while we're calling
1005 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1006 away the string to add_history.
1007 (completion_function): Do completion for readline. (Thanks to
1009 (scm_filename_completion_function): New procedure: Filename
1011 (current_input_getc): New function. Use this one instead of
1012 standard getc from readline.
1014 * throw.c, throw.h (scm_handle_by_throw): New function: This
1015 handler throws errors to next handler on the dynwind chain.
1017 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1019 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1022 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1024 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1026 (scm_procedure_properties): Modified to return arity together with
1028 (scm_procedure_property): Added the read-only property `arity'.
1029 (scm_set_procedure_property_x): It is an error to set the `arity'
1032 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1033 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1035 * procprop.h (scm_sym_arity): New symbol.
1037 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1038 to set the dispatch procedure of an operator or entity object.
1040 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1041 Made procedure slots read-only.
1043 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1044 scm_tcs_cons_gloc case in zero args switch; Fixed args
1045 construction for operators in scm_tcs_cons_gloc case in two args
1048 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1050 * fluids.c: Removed use of assert.h (in order to avoid
1053 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1055 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1057 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1058 change makes the evaluator safer at the cost of evaluation speed.
1059 It handles the case when the user has added a non-immediate
1060 improper end of the application form, e.g., `(+ 0 . x)'.
1061 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1062 minimize the extra cost as much as possible. The new code is
1063 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1064 problem with structs planted directly in the code (e.g. by a
1065 macro). This no longer causes segmentation fault. (Thanks to
1068 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1069 arg `proc' in order to be able to throw errors; New argument
1072 * Removed extra #include "debug.h"
1074 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1076 * scmsigs.c: Declare usleep as returning void on some systems.
1077 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1080 * coop.c (usleep): Return void on some systems.
1082 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1084 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1086 * coop.c: Changed return type of usleep to int.
1088 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1089 isn't found in the OS.
1091 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1092 isn't enabled. (Thought that I had made this change ages ago...)
1094 * iselect.c: Declare bzero if not defined by OS.
1096 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1098 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1099 condition. (Thanks to John Tobey.)
1101 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1102 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1105 * __scm.h: Start the long-term project of moving to POSIX threads.
1106 Phase 1: Classification of all critical sections.
1107 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1108 for A sections. (See comments in __scm.h for details.)
1110 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1111 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1113 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1115 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1116 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1117 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1118 dependencies on $(srcdir)/Makefile.in
1119 $(top_builddir)/config.status in order to avoid circularity.
1121 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1122 from argc if argc was 0 initially.
1124 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1125 in generation of libpath.h.
1127 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1129 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1130 libguile from 2 to 3.
1132 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1134 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1136 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1138 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1139 scm_set_port_column_x, scm_port_filename,
1140 scm_set_port_filename_x): Removed optional arguments. Added
1141 proper argument checking.
1143 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1144 stack size in machine words.
1146 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1147 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1148 to Ole Myren Röhne.)
1150 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1152 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1153 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1155 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1158 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1159 procedure apply: Copy argument lists before pushing them unto the
1160 environment so that the environment won't get mutated due to
1161 manipulation of procedure arguments. This should perhaps be
1162 regarded as a temporary solution until someone finds a more
1163 efficient one. (Thanks to Maciej Stachowiak.)
1165 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1167 * script.c (scm_compile_shell_switches): Use "guile" as default
1168 zero arg if argc is NULL.
1170 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1172 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1173 is zero. (Thanks to Dirk Herrmann.)
1175 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1177 * ports.c (scm_add_to_port_table): First line is now line 0
1178 (was 1). (Interface changed according to suggestion by Per
1181 * backtrace.c (display_header): Add 1 to line and column numbers
1182 when presenting them to the user.
1184 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1185 from debug.c --> eval.c
1187 * eval.h, eval.c (scm_eval_options_interface): New options
1189 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1190 i.e. stacks for new threads.
1192 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1194 * eval.c (unsafe_setjmp): Removed with #if 0.
1196 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1199 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1200 to avoid compiler warnings.
1202 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1204 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1206 * throw.c (handler_message): Print message on current error port
1207 instead of default error port. (Thanks to Maciej Stachowiak.)
1209 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1211 * ports.c (scm_add_to_port_table): allocate in units of
1212 struct scm_port_table *, not struct scm_port_table.
1213 * posix.c (scm_close_pipe): remove the port from the port table
1215 Thanks to Rob Engle for both fixes.
1217 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1219 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1220 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1222 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1224 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1226 * backtrace.c (display_error_body, display_backtrace_body),
1227 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1228 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1229 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1230 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1233 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1234 don't receive the jmpbuf arg anylonger.
1235 (scm_catch): Don't accept a #f tag.
1236 (scm_throw): Check that key is a symbol.
1237 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1239 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1241 * async.c (async_pending): Removed declaration.
1243 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1245 * dynwind.c (scm_wind_chain): New debug function.
1247 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1248 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1249 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1250 extra layer of functions around the body and handler of a thread.
1251 This extra layer makes sure that the handler is called in the
1252 dynamic context of the surround (= empty dynwind list), but under
1253 the *dynamic root* of the body. We can not use the dynamic root
1254 of the surround since that root belongs to another thread => stack
1255 is not handled correctly. It may seem ugly to use this extra
1256 layer, but the extra cost in terms of execution time is really
1257 negligible compared to the total amount of time required to create
1258 a thread, and it would reduce maintainability to duplicate the
1259 crucial and complicated steps performed by cwdr.
1261 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1262 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1263 get re-enabled. The important effect of this is that interrupts
1264 are blocked during thread switching so that thread data structures
1265 don't risk getting messed up by an unfortunate signal.
1266 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1267 seems to do more aggressive optimization which actually move
1268 instructions around in these macros in a fatal way. Therefore:
1269 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1270 just superstitious...)
1271 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1272 This macro should be used instead of SCM_ASYNC_TICK since the
1273 latter doesn't do context switches any more.
1275 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1276 instead of SCM_ASYNC_TICK.
1278 * coop.c, iselect.c: Since thread switches are now performed with
1279 interrupts masked, we can't use the old mechanism of delivering
1280 signals immediately when they arrive. Signals must instead be
1281 delivered when the asyncs run *after* the end of the critical
1282 section in scm_internal_select. But this also means after context
1283 switch so that the signal will be delivered to a different thread.
1284 To avoid this, I have changed the protocol of
1285 coop_wait_for_runnable_thread and friends so that they are allowed
1286 to return the original thread. So, if a signal arrives during
1287 scm_internal_select, we won't any longer be forced do a context
1288 switch, but can remain in the same thread and deliver the signal
1291 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1292 scm_asyncs_pending and made it global.
1294 * iselect.c: Small fixes.
1296 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1297 coop_condition_variable_init, coop_condition_variable_wait,
1298 coop_condition_variable_signal): Changed return type from `void'
1299 to `int'. This is to adhere closer to the pthreads interface.
1300 This, in turn, is part of an attempt to provide C versions of the
1301 mutex and condition variable primitives which can be part of a
1302 frontend to COOP or pthreads.
1304 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1305 coop_condition_variable_destroy): New functions.
1307 * coop-threads.c (scm_wait_condition_variable): Use
1308 coop_condition_variable_wait_mutex.
1310 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1311 Definitions moved to coop-defs.h.
1313 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1314 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1315 scm_cond_destroy): New C interface to mutecis and cond vars.
1317 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1319 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1321 * iselect.c: Now several threads can wait on the same file
1322 descriptor. The behaviour is compatible with OS select: All
1323 threads waiting for the fd return with the same status.
1325 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1327 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1328 Can spawn a thread from application C code.
1330 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1332 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1333 gh_doubles2scm): New functions.
1335 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1337 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1338 commented-out version of gh_eval_str()
1340 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1342 * socket.c (scm_bind): free soka after use.
1344 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1346 * stime.c (tzvar): new variable.
1347 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1348 avoid memory leaks when allocating.
1350 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1352 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1355 * gc.c, tags.h: Doc fixes.
1357 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1359 * eval.c (macro-eval!): Removed. This function was a design bug.
1360 It allowed memoized code to leak out to the scheme level. Most
1361 things that you could do with `macro-eval!' can be done with
1364 1997-12-20 Tim Pierce <twp@skepsis.com>
1366 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1367 scm_fgets now depends on ftell(3) to know how many bytes were
1370 1997-12-15 Tim Pierce <twp@skepsis.com>
1372 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1373 dealing with strings.
1375 1997-12-13 Tim Pierce <twp@skepsis.com>
1377 Make %read-line more suitable for implementing read-line efficiently.
1378 * ioext.c (scm_read_line): Strip the terminating newline from a
1379 string, and return a cons of the string and its terminator.
1381 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1382 of the string that is read is stored in this memory location.
1383 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1384 * genio.c, genio.h (scm_do_read_line): Update caller.
1385 * ports.h (scm_ptobfuns): Update typedef.
1386 * fports.c (scm_fptob, scm_pipob): Update struct.
1388 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1390 * filesys.c (set_element): Return file descriptor.
1391 (fill_select_type): Return the highest file descriptor.
1392 (scm_select): Tell select about the highest file descriptor. On
1393 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1394 Therefore the extra overhead for calculating the maximum fd seems
1395 to be more than compensated. Is this correct? In any case,
1396 scm_internal_select will be much faster with this info.
1397 (scm_select, fill_select_type, set_element): Don't accept any kind
1398 of object in the file descriptor list or vector.
1400 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1402 * iselect.c (finalize_fd_sets): Bugfix.
1404 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1406 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1407 when using scm_internal_select (since we might switch to another
1410 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1412 * simpos.c (scm_system): always define: use sysmissing if not
1413 available. Check for HAVE_SYSTEM instead of _Windows (does
1414 Windows lack system or does it have an unusable one?).
1415 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1416 Let the argument be optional: if not supplied, call system(NULL).
1418 * ports.c (scm_close_port): relax the type check from OPPORTP to
1419 PORTP; closing a closed port is allowed.
1421 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1423 * fports.c (scm_fgets): Return if the last char in a chunk is
1424 newline. When fgets returns a string whose length is `size-1', it
1425 is ambiguous whether a whole line was retrieved, so we must check
1426 explicitly whether a line terminator is present.
1428 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1430 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1431 before taking the CDR. (Thanks to Harald Meland.)
1433 * filesys.c (scm_stat): Slightly optimized.
1435 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1437 * ports.c (scm_close_port): Make sure the port is open before
1440 * guile-snarf.in: Pass args through to gcc in a way that preserves
1441 whitespace boundaries. (Thanks to Greg Badros.)
1443 1997-12-02 Tim Pierce <twp@skepsis.com>
1445 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1446 statement. (Thanks to Doug Evans for pointing this out.)
1448 1997-12-01 Tim Pierce <twp@skepsis.com>
1450 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1452 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1454 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1455 errno macro expansion of this field name. (errno is a C
1456 preprocessor macro on some systems.)
1458 1997-11-29 Tim Pierce <twp@skepsis.com>
1460 * iselect.c: Doc fix.
1462 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1464 * init.c (scm_start_stack): Removed initialization of
1465 scm_the_last_stack_var.
1467 * backtrace.h: Declare scm_the_last_stack_var.
1469 * backtrace.c: Define scm_the_last_stack_var.
1471 * root.c (mark_root): Don't mark the_last_stack_var.
1473 * root.h (scm_root_state): Removed the_last_stack_var.
1475 * throw.c: Added #include "fluids.h"
1476 (ss_handler): `the-last-stack' is now a fluid.
1478 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1479 --> the_last_stack_fluid.
1481 * backtrace.c: Added #include "fluids.h"
1482 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1483 (scm_backtrace): `the-last-stack' is now a fluid.
1485 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1486 after scm_init_fluids.
1488 1997-11-28 Tim Pierce <twp@skepsis.com>
1490 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1492 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1493 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1495 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1497 * iselect.c (coop_next_runnable_thread,
1498 coop_wait_for_runnable_thread): Disable interrupts so that no
1499 async is executed before a potential error_revive.
1500 (scm_internal_select): Disable interrupts during the parts of the
1501 code which manipulate the sleep queue and the file descriptors.
1503 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1505 * Makefile.am: Added iselect.c and iselect.h.
1507 * coop.c (coop_qinit): Initialize fields used by
1508 scm_internal_select.
1509 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1510 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1511 replacement in iselect.c.
1512 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1513 coop_join): If GUILE_ISELECT enabled, use
1514 coop_wait_for_runnable_thread instead of
1515 coop_next_runnable_thread.
1516 (usleep, sleep): New replacements for system functions if
1517 GUILE_ISELECT is enabled.
1519 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1521 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1523 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1524 iselect.h. Implement Scheme level `select' using
1525 scm_internal_select. (See NEWS.)
1527 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1529 * init.c: Call scm_init_iselect.
1531 * iselect.h, iselect.c: New files. Implements
1532 scm_internal_select. (See NEWS.)
1534 1997-11-27 Tim Pierce <twp@skepsis.com>
1536 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1537 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1538 and scm_must_free, since ultimately the string returned will be copied
1539 by scm_makfrom0str anyway. Also, read any characters that may have
1540 been pushed onto the port with scm_ungetc.
1541 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1542 * ioext.c (scm_read_line): Free string after Guilifying it.
1543 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

1554 gh_repl (argc, argv).
1556 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1558 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1559 and to invoke scm_shell().
1560 (gh_launch_pad): took out the loading of boot-9.scm from here,
1561 since it is probably best to let the user control that. In fact,
1562 gh_repl() now invokes scm_shell() which does that.
1564 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1566 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1569 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

1588 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1589 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1591 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1593 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1594 configure.in was changed).
1596 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1598 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1599 * Makefile.in: Regenerated.
1601 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1603 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1604 OPORT is an `open' port, not an output port.

1612 scm_set_port_filename_x, scm_port_mode,
1613 scm_close_all_ports_except, scm_set_current_output_port,
1614 scm_set_current_error_port): Likewise
1615 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1616 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1618 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1619 * backtrace.c (display_backtrace_body): Likewise
1620 * fports (scm_setvbuf): Likewise
1621 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1628 Minor problems with substring-related tag changes.
1629 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1630 exactly what we want to leave in to detect substrings.
1631 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1632 * tags.h: Fix diagrams and comments describing the S tag bit;
1633 remove vestigial remarks about the D tag bit.
1634 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1635 * strings.c: Formatting tweaks.
1637 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1638 variable first; then SCHEME_LOAD_PATH, with a warning message.
1639 (scm_parse_path): New function.
1640 * script.c: Doc fixes.
1642 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1644 Readline support, from Daniel Risacher.
1645 * readline.c, readline.h: New files.
1646 * init.c: #include "readline.h".
1647 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1648 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1649 * Makefile.in: Regenerated.
1650 * scmconfig.h.in: Regenerated, after change to ../configure.
1652 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1654 * gh.h: gh_vector_set -> gh_vector_set_x
1656 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1658 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1659 with the ! -> _x mapping when going from Scheme to C.
1661 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1663 * gh.h (gh_reverse):
1671 (gh_assoc): added these gh_ functions implemented as macros.
1673 * gh_predicates.c (gh_null_p):
1674 (gh_string_equal_p): added these two missing predicates.
1676 * gh_list.c (gh_append):
1681 (gh_set_cdr_x): added these routines as I go through and try to
1682 complete the picture R4RS functions that should be mirrored in the
1685 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1687 * tags.h (scm_tc7_substring): Changed the comment and code to
1688 conform with the changes below. Folks! We have suddenly two new
1689 free tc7 codes!!! Jummy, jummy!
1691 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1693 * Makefile.in: Rebuilt.

1714 (scm_tc7_mb_string): Removed.
1715 (scm_tc7_mb_substring): Removed.

1718 Don't include "mbstrings.h".
1719 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1720 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1722 Don't include "mbstrings.h".
1723 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1724 (SCM_SYMBOL_SLOTS): Define as 4.

1726 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1727 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1728 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1729 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1749 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1751 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1753 * gh_test_c.c (c_vector_test): some improvements on the vector
1756 * gh.h (gh_vector): this used to exist but do the wrong thing.
1757 Now it (almost) does the right thing, though it takes a list
1758 instead of the individual arguments. I need to see how it could
1760 (gh_list_to_vector): added this function as a macro. Corresponds
1761 to Scheme's (list->vector ...).
1762 (gh_vector_to_list): added this function as a macro. Corresponds
1763 to Scheme's (vector->list ...).
1765 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1766 gh_vector_ref, so that it resembles the Scheme routines more.
1767 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1768 resembles the Scheme routines more.
1769 (gh_make_vector): this used to be (stupidly) called gh_vector().
1770 This is the right name, since it does the same thing as the Scheme
1771 (make-vector ...) procedure.
1773 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1775 * ports.h: #include "libguile/print.h"

1778 Some indentation fixes.
1780 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1781 longer a user field; New field: class_flags.
1783 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1785 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1787 * gh_data.c (gh_bool2scm): new function which replaces
1788 gh_int2scmb(), which is now tagged as obsolete.
1790 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1792 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1793 macros should by convention not test for NIMPness.)
1794 (SCM_COERCE_OPORT): Adjust indentation.
1796 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1797 SCM_NIMP test before SCM_PRINT_STATE_P.
1799 * struct.c, struct.h, gc.c: Renamed:
1800 scm_struct_i_layout --> scm_vtable_index_layout
1801 scm_struct_i_vcell --> scm_vtable_index_vcell
1802 scm_struct_i_vtable --> scm_vtable_index_vtable
1803 scm_struct_i_printer --> scm_vtable_index_printer
1804 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1806 * struct.c (scm_print_struct): Use new printer slot; Default
1807 printing: Also output hex code of vtable so that type identity
1808 will be indicated as well.
1809 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1810 Removed struct_printer_var; Removed struct-vtable-offset;
1811 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1812 vtable-offset-user): New constants.
1814 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1815 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.

1817 the type represented by this vtable.
1819 * print.c (scm_iprin1): Don't print arguments of macro
1820 transformers. (They are always: exp env.); Bugfix: Unmemoize
1821 transformer source with correct environment.
1823 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1825 Streamlining of call-with-dynamic-root:
1827 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1828 there is now only one catch.
1829 (cwdr_outer_body): Removed.
1830 (cwdr_handler): New function.
1831 (scm_internal_cwdr): New function to perform the function of cwdr
1832 but take args that are more useful to C code. Also, the handler
1833 is now invoked *outside* of the new dynamic root, like the docs
1834 say. We no longer have to catch absolutely all errors, the caller
1835 is responsible for using a handler that does not throw, if he
1837 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1838 * root.h (scm_internal_cwdr): New prototype.
1840 Even more but risky streamlining:
1842 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1843 allocation of the jumpbuf of a root continuation. The changes
1844 below are controlled by it. They are now deactivated.
1845 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1846 the JMPBUF of the scm_rootcont to NULL before returning.
1848 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1849 when they are non-NULL.
1850 (scm_gc_mark): Likewise, mark only when non-NULL.
1852 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1853 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1855 * gc.c (scm_done_malloc): New function.
1856 gc.h (scm_done_malloc): New prototype.
1858 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1865 a certain value is acceptable as a port argument.
1866 (scm_print_state_vtable): New variable.
1867 (scm_free_print_state): Set `revealed' field to false.
1868 (scm_iprin1): Call user supplied closure printer with
1869 scm_printer_apply. Print in the traditional way when there isn't
1870 one or when it returns #f.
1871 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1872 Accept a port/print-state pair in addition to just a port.
1873 (scm_prin1): Don't return the print_state to the pool when it has
1875 (scm_printer_apply): Set `revealed' field of print_state to true.
1876 (scm_init_print): Set scm_print_state_vtable.
1877 (print_state_fluid, print_state_fluid_num): Removed.
1879 * throw.h (scm_handle_by_proc_catching_all): New prototype
1880 throw.c (scm_handle_by_proc_catching_all): New function
1882 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1884 * Makefile.in: Regenerated with automake 1.2c.
1886 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1888 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1889 was looping endlessly.
1891 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1893 * strports.c (scm_eval_string): Don't close the port.
1895 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1896 former returns a nice normal integer. (Thanks to Daniel
1899 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1901 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1902 makefile variable as a build parameter called LIBS. The
1903 build-guile program will use this, for the time being.
1904 * Makefile.in: Regenerated.
1906 Thanks to Shiro Kawai:
1907 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1908 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1911 * Makefile.in: Regenerated with automake 1.2a.
1913 * script.c (scm_compile_shell_switches): If we hit the -c or --
1914 arguments, don't set the car of (command-line) to scm_usage_name,
1915 the prettified name of the guile executable; give it the full
1916 path, the way shells usually handle $0.
1918 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1920 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1921 Scheme-level name `array-map' and renamed `serial-array-map' to
1922 `serial-array-map!'.
1924 * backtrace.c: Introduced exception handlers which now enclose
1925 `display-error' and `display-backtrace' so that error reporting
1926 won't get into infinite loops if an error occurs during displaying
1927 of the error. This can very easily happen with user supplied
1928 print call-back routines.
1930 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1932 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1933 the names `serial-array-map' and `array-map' should be removed.)
1935 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1937 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1938 Added #include "objects.h"
1940 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1941 Add #include "feature.h".
1943 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1944 (modinclude_HEADERS): Added objects.h.
1946 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1947 This test is needed at many places in the code and should be
1948 abstracted. (Motivated by the need of this test in libguiletk.)
1950 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1951 (scm_eval_string), load.c (scm_primitive_load,
1952 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1953 Use SCM_EOF_OBJECT_P.
1955 * eval.c (scm_init_eval): Add feature `delay'.
1957 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1959 * scmhob.h: Removed.
1961 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1963 * list.h (SCM_LISTn): New macros. Make list creation in C code
1964 prettier. The idea comes from STk.
1966 * sequences.h, sequences.c, append.h, append.c: Removed. These
1967 files implemented non-R4RS operations which would encourage
1968 non-portable programming style and less easy-to-read code.
1970 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1973 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1974 sequences.h, #include append.h.
1976 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and

1981 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1983 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1985 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1987 * eval.c: Added #include "objects.h"
1989 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1992 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1993 adjacent smob numbers.
1995 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1997 * procprop.h: Added declaration of scm_i_inner_name.
1999 * gsubr.c: New global symbol scm_i_inner_name.
2001 * debug.c (scm_procedure_name): Try procedure property
2002 `inner-name' if `name' fails.
2004 * print.c (scm_iprin1): Use scm_macro_name.
2006 * eval.c (scm_m_define): Give names to macros as well; Only the
2007 first top-level definition gives a procedure/macro a name.
2008 Otherwise confusing names can turn up in backtraces.
2009 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2010 `name'; Give names to macros as well.
2012 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2013 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2016 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2018 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2020 (prinmacro): Removed. The code has been moved/merged into print.c
2021 in order to decrease code redundancy. We want macros to print in
2022 a way equivalent to procedures, and it would be silly to duplicate
2023 the required code. (We don't want to maintain two places.)
2024 (macrosmob): Print field is now a NULL pointer.
2026 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2027 scm_macro_transformer): New prototypes.
2028 (scm_tc16_macro): Declared.
2030 * print.c (scm_iprin1): Added code for printing of macros. Macros
2031 are now printed in a way equivalent to procedures.
2033 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2035 * procs.h (scm_closure_p): Added declaration.
2037 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2039 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2040 Shouldn't pass "heap" as the subr name.
2042 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2044 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2045 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2046 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2047 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2048 SCM_BOOL_T. Any non-false value is true.
2050 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2052 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2053 scm_gensym): Added prototypes.
2055 * symbols.c (scm_gensym): New function. This will speed up
2056 certain types of applications (such as macro systems) which
2057 generate lots of symbols.
2059 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2061 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2063 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2065 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2066 specifier, since (2) or (2 . 3) would cause SEGV.
2067 (scm_transpose_array): more argument checking fixes.
2069 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2071 * Makefile.in: Regenerated.
2073 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2075 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2077 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2079 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2081 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2083 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2084 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2087 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2088 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2089 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2090 scm_array_p, scm_array_rank, scm_array_dimensions,
2091 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2092 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2093 scm_array_prototype): Added case scm_tc7_wvect.
2095 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2097 * errno.h: prototype for scm_strerror.
2098 * error.c (scm_strerror): new procedure.
2100 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2102 * list.c (scm_list_append_x): Allow non-pair as last argument.
2103 This is consistent with the R4RS append and is probably the
2104 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2106 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2108 * stime.h: prototype for scm_times.
2109 * stime.c (scm_times): new procedure.
2110 * ioext.c (scm_fseek): if the first argument is a file descriptor
2112 (scm_ftell): if the first argument is a file descriptor call lseek
2114 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2115 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2117 (scm_chown): if the first argument is a port or file descriptor,
2119 (scm_truncate_file): new procedure.
2120 Add DEFER/ALLOW INTS to a few other procedures.
2121 (scm_fsync): new procedure.
2122 (scm_open_fdes): new procedure.
2123 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2125 (scm_fcntl): the first argument can now be a file descriptor. The
2126 third argument is now optional.
2128 * posix.c (scm_execl, scm_execlp): make the filename argument
2129 compulsory, since omitting it causes SEGV.
2130 (scm_sync): return unspecified instead of #f.
2131 (scm_execle): new procedure.
2132 (environ_list_to_c): new procedure.
2133 (scm_environ): use environ_list_to_c. disable interrupts.
2134 (scm_convert_exec_args): take pos and subr arguments and
2135 improve error checking.
2137 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2139 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2140 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2141 argument to SCM_ASSERT. Furthermore, the name of the function
2142 should be passed as first argument when signalling
2143 SCM_WNA. (Thanks to Thomas Morgan)
2145 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2146 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2147 dispatches on the number of actual args has a default case
2148 reporting an internal error. This is a vestige from a version
2149 that mallocated a SCM vector to hold the arguments. In the
2150 current version this check is too late: if it ever happens we will
2151 have already overstepped the bounds of the array.
2153 Also, the patch [...] adds a check for too many actual arguments."
2155 mdj: Removed check for "internal programming error".
2157 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2159 * gh_io.c (gh_write): New function.
2161 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2162 throw.c (scm_internal_stack_catch): New sibling to the other catch
2163 functions. Code moved from gh_eval.c.
2164 throw.h: Added header.
2165 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2166 scm_internal_stack_catch.
2168 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2170 * ioext.h: fix up prototypes.
2171 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2172 Scheme name is now dup->fdes.
2173 (scm_dup_to_fdes): make the second argument optional and
2174 fold in the functionality of scm_primitive_dup.
2175 (scm_primitive_dup): deleted.
2177 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2179 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2180 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2181 ultrix are defined. Use setvbuf instead of setbuf.
2182 (scm_setvbuf): new procedure.
2183 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2184 (scm_setfileno): moved from ioext.c.

2196 state as nested data while they are printed.
2197 (print_state_fluid, print_state_fluid_num): New variables.
2198 (scm_init_print): Initialize them.
2199 (scm_iprin): If print_state_fluid carries a print_state, use that
2200 instead of creating a new one.
2201 (scm_printer_apply, apply_stub, struct apply_data): New
2202 definitions to help with calling printer functions written in
2204 * print.h (scm_printer_apply): New prototype.

2217 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2218 SCM_ASSERT: arg comes before pos.
2220 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2222 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2223 to a list of length zero correctly.
2225 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2241 * ioext.h: removed scm_duplicate_port prototype.
2243 * ioext.c (scm_primitive_dup2): return the new file descriptor
2244 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2246 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2247 stream has been set.
2248 (scm_duplicate_port): deleted, there's now an implementation in
2250 (scm_primitive_dup2): do nothing if newfd == oldfd.
2252 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2254 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2261 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2263 * ports.h: prototypes too.
2264 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2266 * fports.h: prototype too.
2267 * fports.c (scm_evict_ports): moved from ioext.c.
2269 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2271 * ports.c (scm_close_port): return a boolean instead of unspecified.
2272 throw an error if an error other than EBADF occurs.
2274 * filesys.h: scm_close prototype.
2275 * filesys.c (scm_close): new procedure, can close file descriptors
2276 and ports (scsh compatible).
2278 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2281 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2283 * fluids.c, fluid.h: New files.
2284 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2285 (modinclude_HEADERS): Added "fluids.h"

2294 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2295 unique for the new root when it has a parent.
2297 * smob.h: Include "libguile/print.h" to make scm_print_state
2300 * dynl.c (free_dynl_obj): New function to free the dynamic object
2301 data. (dynl_smob): Use it.
2302 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2303 the dynamic object data below the linking of the object to avoid
2304 memory leak when the linking code throws an error. Now the code
2305 leaks a whole dynamically linked library when must_malloc throws,
2306 but that should be much less likely.
2308 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2310 Changes to compile under gnu-win32, from Marcus Daniels:

2312 (scm_localtime): Change SCM_EOF to SCM_EOL.
2313 (scm_mktime): Likewise.

2326 (scm_setpwent): For setpwent.
2327 (scm_setegid): For setegid.
2328 * net_db.c (scm_inet_netof): Don't include unless support

2348 think this is left over from the (eq? '() #f) days.
2350 * read.c (recsexpr): Give this a dummy definition if
2351 DEBUG_EXTENSIONS isn't #defined.
2353 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2355 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2365 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2366 alloca.lo will be included in @LIBLOBJS@. Something better than
2367 this should be possible.
2368 * Makefile.in: Regenerated.
2370 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2372 * simpos.h: prototype for scm_primitive_exit.
2373 * simpos.c (scm_primitive_exit): new procedure, terminates the

2378 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2379 argument and logior its components together, so the user doesn't
2380 have to do this explicitly. Also, if regexp/basic is supplied, then
2381 turn off REG_EXTENDED.
2382 (scm_init_regex_posix): New regexp/basic symbol.
2383 (REG_BASIC): #define this if it is not already present.

2399 * Makefile.in: Regenerated.
2401 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2402 flag; I don't think we support it.
2403 (scm_make_regexp): Make sure the user doesn't pass the
2406 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2408 (scm_init_regex_posix): Define constants for the REG_mumble flags;

2419 * load.c: #include "alist.h".
2420 (init_build_info): New function.

2426 * root.c: Establish a reliable catch-all handler for the new root.
2427 After all the Scheme handler function might signal an error too,
2428 and we don't want to lose that.
2429 (cwdr_inner_body): Renamed from cwdr_body.
2430 (cwdr_outer_body): New function, to establish the user's handler,
2431 and pass control to cwdr_inner_body.
2432 (cwdr): Establish the reliable catch-all handler here, and pass
2433 control to cwdr_outer_body.
2434 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2435 the user's handler through to cwdr_outer_body.

2442 across this. Only works on GCC. Otherwise, we hope for the best.
2443 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2444 the feeling that real thread systems will not need this...
2446 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2448 Try to detect when people are using one version of libguile and a

2460 primitive definitions under their Scheme names.
2462 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2463 1:2. Helps avoid confusion between installed and uninstalled libs.
2465 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2468 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2469 backslash from definition; this should be used like: GDB_INTERFACE;
2471 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2473 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2474 new port unbuffered until its stream has been set.
2476 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2478 * ports.h: new prototype.
2479 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2481 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2483 Make things compile neatly under Sun's C compiler.
2484 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2485 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2486 unsigned, because that's what the ANSI function takes.
2487 * extchrs.h (xmbtowc): Corresponding change to prototype.
2488 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2490 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2491 argument plain char *.
2492 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2494 * tag.c (scm_tag): Remove unreachable statement.
2495 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2496 top of the word, it should be unsigned.
2498 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2499 is defined, to avoid warnings; it's only used in the
2500 conflict-checking code. Which might go away anyway.
2501 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2502 conditionals; put the label definition in an #if too, to stifle
2505 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2506 ChangeLog-threads in the distribution.
2507 * Makefile.in: Regenerated.
2509 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2511 * guile-snarf.in: Changed regexp to support CPPs that insert
2512 whitespace between lexical tokens (which munges the `%%%' snarf
2515 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2517 * load.c (scm_init_load_path): Append $(datadir)/guile to
2518 %load-path, so modules do not have to be installed in Guile's
2519 current version directory.
2521 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2523 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2524 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2525 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2526 call the sysdep functions with deferred ints.
2527 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2528 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2529 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2532 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2535 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2537 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2539 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2541 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2544 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2546 * eval.c (scm_lookupcar1): New procedure to cope with a race
2547 condition during lookup (when using threads).
2548 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2549 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2552 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2554 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2555 supplied. (Change from Tim Pierce.)
2557 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2559 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2560 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2561 default and not `()'. `#f' is the canonical non-value in Scheme,
2564 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2566 * struct.c (struct_printer): New variable that holds a handle on
2567 the Scheme variable *struct-printer*. This variable can be set by
2568 Scheme code to override the printing of structures.
2569 (scm_print_struct): If struct_printer is set, call it. If it is
2570 not set, or returns #f, print the structure in the old fashion.
2571 Include "eval.h" for scm_apply.
2573 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2575 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2576 scm_struct_i_n_words to get the number of fields, not
2577 -scm_struct_n_extra_words.
2579 On the route to fancier struct printing:
2580 * struct.c (scm_print_struct): New function to print a structure.
2581 Include "genio.h" to support it. This function doesn't do
2582 anything interesting right now, but I think it should be here
2584 * struct.h: Include "print.h" and add prototype for
2586 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2587 print structures ourself.
2589 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2591 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2592 before applying the handler in case it doesn't return.
2594 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2596 * scmsigs.h, async.h: updated.
2598 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2601 * posix.c (scm_uname): interpret only negative values as an error.
2602 Solaris normally returns a positive value.
2604 * script.c (scm_compile_shell_switches): if we are not going into
2605 an interactive repl, set scm_mask_ints to zero so that asyncs can
2608 * simpos.c (scm_system): don't ignore/unignore signals around
2611 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2614 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2615 done in boot-9.scm instead.
2617 * scmsigs.c, async.c: Major rewriting of signal handling code.
2618 (scm_sigaction): new procedure.
2619 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2621 (scm_raise): return unspecified, throw error on failure.
2623 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2625 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2626 feature, to help boot-9.scm decide whether to import the regex
2629 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2631 * eval.c: Include scmconfig.h at the beginning of the file so that
2632 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2635 * regex-posix.c: #include "_scm.h" before conditionally #including
2636 <regex.h>; the former defines HAVE_REGCOMP.
2638 * regex-posix.c: #include <regex.h> conditionally, so the file is
2639 CPP'able (for dependency scanning) even on systems that don't have
2642 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2644 Add new R4RS-compliant syntax for keywords.
2645 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2646 regardless of the setting of the `keywords' read option.
2647 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2648 can be re-read no matter what the setting of the `keywords' read
2651 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2653 Add support for POSIX regular expressions.
2655 * regex-posix.c, regex-posix.h: New files. (Some code
2656 is taken liberally from rx/rgx.c in the old Guile dist.)
2658 * init.c: Include regex-posix.h.
2659 (scm_boot_guile_1): Call scm_init_regex_posix.
2661 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2662 Add regex-posix.[ch] sources.
2663 * Makefile.in: Regenerated.
2665 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2666 to do this automatically? It didn't for me, bleh.)
2668 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2670 * fports.c (print_pipe_port): New function.
2671 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2672 latter doesn't even take the right arguments.
2674 * Makefile.am: Increment shared lib revision number. I think
2675 sometimes the uninstalled Guile finds the installed shared lib;
2676 Gord says doing this might help. As things turned out, I can't
2677 say whether it does.
2678 * Makefile.in: Regenerated.
2680 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2681 passing it as the closure argument to scm_boot_guile. (Bill
2684 * ports.c (print_void_port, putc_void_port, puts_void_port,
2685 write_void_port, flush_void_port, getc_void_port, close_void_port,
2686 noop0): Use ANSI prototypes instead of K&R declarations, so the
2687 initialization of void_port_ptob gets aggressively type-checked.
2688 Fix arguments of print_void_port and write_void_port. (Bill

2722 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2724 * script.c (scm_find_executable): Use prototype-style definition
2725 here; apparently it's not quite right to have const in a prototype
2726 and then use a K&R declaration. I wonder if stuff like this will
2727 go away if we compile with -Wrequire-prototypes, or whatever that
2728 is... (Bernard URBAN)
2730 * scmhob.h: New text from Bernard URBAN.
2732 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2734 * script.c: Don't #define const on hpux. Configure takes care of
2735 this. (Thanks to Larry Schwimmer.)
2737 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2738 decide whether to #include <unistd.h>, instead of listing a bunch
2739 of systems. Don't #include stdio twice. Removed dyked-out
2740 definition of scm_find_impl_file.
2742 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2744 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2745 library version info to 1:0.
2746 * Makefile.in: Regenerated.

2752 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2753 throw.c: Update copyright years; these files have been worked on
2754 significantly in 1997, but only had copyright years for 1996.
2755 Also, change name of copyright holder on some from Mikael
2756 Djurfeldt to Free Software Foundation; he has signed papers
2757 assigning the changes to the FSF.
2759 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2760 reason not to give the user the option.
2762 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2763 Return #f on end-of-file when scanning table (i.e. when called
2764 with no arguments). Try to catch errors, when we can.
2765 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2767 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2768 external declarations. These are useful.
2770 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2772 * posix.c: don't include <sys/select.h> or define macros for
2773 select, since they were not used in this file.
2775 * filesys.c (scm_select): make the fifth parameter microseconds,
2776 not milliseconds. let the fourth parameter be either a real value
2777 or an integer or #f. The first, second and third arguments can
2778 now be vectors: the type of the corresponding return set will be
2780 (set_element, get_element): new static procedures.
2782 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2784 * strports.c (scm_eval_string): New function.
2785 (scm_eval_0str): Trivially re-implemented in terms of
2787 * strports.h (scm_eval_string): New extern decl.
2789 * net_db.c (h_errno): Add extern decl for this.
2791 * fports.c (local_pclose): New function.
2792 (scm_pipob): Use it in the initializer here.
2795 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2796 Use a meaningful error message when signalling an error. For
2797 this, scm_gethost must check h_errno rather than errno.
2799 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2801 * Makefile.in: Regenerated, using automake-1.1p.
2803 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2805 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2806 not SCM_UNSPECIFIED.
2808 * script.c (scm_compile_shell_switches): don't append (quit) if
2810 (scm_shell): call scm_exit_status and exit on the result of the
2813 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2815 Ensure that shared substrings are handled properly when passed to
2816 a system call or other foreign function. Many thanks to Tim
2818 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2819 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2820 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2821 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2833 SCM_COERCE_SUBSTR to make sure shared substrings are
2836 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2838 * error.c (scm_error): Add newline to error message.
2840 * init.c (scm_init_standard_ports): Doc fix.
2842 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2844 * dynl-shl.c: Completely replaced with new code from Bernard
2847 * script.c (scm_ice_9_already_loaded): New variable.
2848 (scm_compile_shell_switches): Use it.
2850 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2852 * filesys.c (scm_input_waiting_p): add missing third argument to

2856 calling gmtime in case they share a buffer.
2857 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2860 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2862 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2864 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2866 * Makefile.am (check-local): New target, which causes 'make check'
2867 to run gh_test_c and gh_test_repl, with some trivial input.
2868 * Makefile.in: Rgnrtd.
2870 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2872 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2875 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2877 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2878 sure how this was supposed to work.
2879 (scm_async_click): don't send SCM_TICK_SIGNAL.
2880 (scm_init_async): don't initialize %tick-thunk.
2882 * the following change doesn't affect the Scheme interface:
2883 gc-thunk is called at the end of garbage collection. however it's
2884 no longer implemented by pretending it's a signal.
2886 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2887 system async corresponding to scm_gc_thunk.
2888 * async.h: declare scm_gc_async.
2889 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2890 gc-thunk directly, instead of going through a signal handler.
2891 (scm_gc_async): new variable, points to the GC system-async.
2892 (scm_init_async): save the GC async as scm_gc_async instead
2893 of using system_signal_asyncs.
2894 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2896 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

2899 Don't screw up if we're interrupted.
2900 * Makefile.in: Regeneradet.
2902 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2904 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2906 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2907 we're not using AM_INIT_GUILE_MODULE any more.
2908 * Makefile.in: Reneregated.
2910 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2912 Functions for finding variable bindings, grace à Tim Pierce.

2916 Get 'make dist' to work again.
2917 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2918 * Makefile.in: Regenerated, like a surry without a fringe on top.
2920 Changes for reduced Guile distribution: one configure script,
2922 * configure.in, configure: Removed.
2923 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2924 real configure script lives.
2925 * Makefile.in, scmconfig.h.in: Regenerated.
2927 * init.c: #include "script.h", to get prototype for script.c's
2930 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2932 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2933 scm_must_malloc, not raw malloc.
2935 * script.c (scm_compile_shell_switches): Dyke out debugging output
2938 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2940 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2942 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2943 system has them. Hope this is safe. Previously
2944 sys/timeb.h was included if HAVE_FTIME was defined or if
2945 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2946 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2948 * ioext.c (scm_setfileno): add missing third argument to
2949 scm_misc_error call.
2951 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2953 * eq.c (scm_equal_p): Correctly compare strings of different
2954 varieties. (Thanks to Tim Pierce.)
2956 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2958 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2959 #! block comment must occur on a line all by itself.
2961 Move most of the guts of shell command processing into libguile,
2962 so guile.c can be very small (and eventuallly auto-generated. (I
2963 mean, generated mechanically, not self-generated. Hmm.))
2964 * guile.c, script.c, script.h: New source files.
2965 * init.c (scm_boot_guile_1): Call scm_init_script.
2966 * libguile.h: #include "script.h".
2967 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2968 targets, for new executable.
2969 (libguile_la_SOURCES): Mention script.c.
2970 (modinclude_HEADERS): Add script.h.
2971 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2972 not dynamic linking is enabled. This is because we're generating
2973 executables now. Move CY_AC_WITH_THREADS call after those, so the
2974 values of cy_cv_threads_libs captures the libs chosen above.
2975 * Makefile.in, configure, aclocal.m4: Regenerated.
2977 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2978 We don't maintain this interface any more, and it just confuses
2981 * alloca.c: #include <scmconfig.h>, not <config.h>.
2982 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2983 it'll get included in disties.
2985 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2987 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2988 be distributed, because they confuse people.
2989 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2991 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2993 * configure.in: check for presence of gethostent (not present on
2994 OpenBSD by default).
2995 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2996 * configure, scmconfig.h.in: Regenerated.
2998 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3000 * backtrace.c (scm_backtrace): Split message string across
3001 newlines properly. GCC is more tolerant of this than other
3004 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3006 Merge threads directory into libguile.
3007 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3008 threads.h: New source files.
3009 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
3010 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3012 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3013 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3014 coop-threads.c.cygnus, coop-threads.h.cygnus.
3015 * configure.in: If we're using threads, include threads.o in
3017 * _scm.h, libguile.h: threads.h lives in this directory now.
3018 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3019 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3020 currently used, but brought along for information's sake.
3021 * ChangeLog-threads: log from old 'threads' directory.
3022 * Makefile.in, configure: Rebuilt.
3024 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3026 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3029 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3031 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3033 Merge GH interface library into libguile.
3034 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3035 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3036 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3037 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3039 (EXTRA_libguile_la_SOURCES): ... here.
3040 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3041 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3042 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3043 New variables, describing how to build the gh test programs.
3044 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3045 build the test programs, and we probably should have been linking
3046 libguile.la against them all along, to support AIX shared libs.
3047 Add cflags for threads to CFLAGS; add libs for threads to new
3048 variable THREAD_LIBS, used in Makefile.am.
3049 * ChangeLog-gh: log from old `gh' subdirectory.
3050 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3052 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3054 * acconfig.h: Undo change of Apr 9; including the definition of
3055 PACKAGE in the guile headers conflicts with applications' own
3057 * scmconfig.h.in: Regenerated.
3059 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3063 * filesys.h: Added prototype.
3065 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
3066 when PROC is receiving no arguments.
3068 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3070 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3071 have S_IFSOCK. This is the case under Ultrix.
3073 * posix.c (scm_status_exit_val, scm_status_exit_val,
3074 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3075 Ultrix versions of WIFSTOPPED, etc., which assume that their
3076 arguments are lvalues (hmm).
3078 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3080 * eval.c: Doc fixes.
3082 * throw.c: Doc fixes; rearranged.
3084 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3086 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3088 * acconfig.h: Added entry for PACKAGE.
3089 * scmconfig.h.in: Regenerated.
3091 Changes to work with automake-1.1n, which has better libtool support.
3092 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3093 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3095 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3097 * Makefile.in: Rebuild.
3099 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3101 * stime.c (scm_mktime): take an optional zone argument.
3102 (scm_localtime): check putenv return value.
3103 (scm_strftime, scm_strptime): moved from posix.c. move #include
3105 stime.h, posix.h: update prototypes.
3106 (bdtime2c, setzone, restorezone): new static procedures.
3107 (scm_mktime, scm_strftime): use them.
3108 (scm_strftime): don't call mktime before strftime. Use
3109 filltime for return value.
3110 (filltime): convert NULL zname to #f.
3111 (scm_strptime): return a count of characters consumed, not
3112 the remaining string.
3114 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3116 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3117 (scm_mktime): likewise.
3119 Uncomment localtime and mktime.
3121 * configure.in: add AC_STRUCT_TIMEZONE.
3123 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3125 * stime.c (scm_init_stime): don't define ticks/sec.
3126 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3127 return value problem and is still portable.)
3129 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3131 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3132 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3133 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3134 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3135 cpp_err_symbols.c): Corresponding changes.
3136 * Makefile.in: Regenerated.
3138 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3140 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3141 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3142 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3143 * putenv.c: new file, from sh-utils 1.12.
3145 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3146 since allocation isn't for Scheme objects.
3147 (scm_putenv): copy strings before placing in the environment.
3149 * stime.c (scm_current_time): throw an error if time returns -1,
3150 instead of returning #f.
3151 (scm_get_internal_real_time, scm_get_internal_real_time): use
3152 scm_long2num for return value instead of SCM_MAKINUM.
3154 * stime.h: prototypes updated.
3156 * stime.c (scm_time_in_msec): apparently unused, deleted.
3158 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3160 * configure.in: check for gettimeofday.
3162 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3163 which may be more usefully portable than a gettimeofday interface.
3165 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3167 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3169 * Makefile.in: Regenerated.
3171 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3173 * stime.c (filltime): recovered static procedure.
3174 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3177 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3178 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3180 * posix.c (scm_mknod): split the mode argument into type and perms
3181 arguments, like the extra fields returned by stat.
3183 * fports.c (scm_pipob): set the close, free and print procedures.
3184 (scm_close_pipe): new procedure.
3186 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3187 define them in boot-9.scm
3189 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3191 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3192 wan't defined. Don't include fd.h.
3194 * Previously fd.h was regenerated whenever configure was run,
3195 forcing a couple of files to be recompiled.
3197 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3198 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3199 Check for _fileno as well as _file.
3201 * ioext.c: don't fd.h.
3202 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3205 * Change the stratigy for getting information about errno
3206 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3207 generating lists of symbols during the build process, which will
3208 not always work, include comprehensive lists in the distribution.
3209 To help keep the lists up to date, the "check_signals" and
3210 "check_errnos" make targets can be used.
3212 * configure.in: don't check for a command to extract errno codes.
3213 * Makefile.am: update file lists, remove errnos.list and errnos.c
3214 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3215 check_errnos targets.
3216 (CLEANFILES): remove errnos.c and errnos.list, add
3217 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3218 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3219 * errnos.default: deleted.
3220 * cpp_signal.c: new file.
3221 * cpp_errno.c: renamed from errnos_get.c.
3222 * cpp_err_symbols, cpp_sig_symbols: new files.
3223 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3224 * error.c (scm_init_error): #include cpp_err_symbols instead of
3226 * posix.c (scm_init_posix): don't intern signal symbols. #include
3229 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3231 * strop.c (scm_i_index): allow the lower bound to be equal to the
3232 length of the string, so a null string doesn't always give an error.
3234 * posix.h: new prototypes.
3235 * posix.c (scm_status_exit_val, scm_status_term_sig,
3236 scm_status_stop_sig): new functions, as in scsh. They break down
3237 process status values as returned by waitpid.
3239 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3241 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3242 configure doesn't know about it.
3244 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3246 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3248 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3249 which defines C variables with global linkage.
3251 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3253 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3256 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3258 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3259 has time to check why this doesn't work well with continuations.
3261 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3263 * Fix shell syntax error; some shells won't tolerate
3264 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3266 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3268 * posix.c (scm_uname): throw an error if uname fails instead
3271 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3273 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

3280 * acconfig.h: Removed PACKAGE.
3282 * scmconfig.h.in: Regenerated.
3284 * snarf.h: g++ says it's non-portable not to specify the first
3285 argument in a varargs declaration. I introduced the first
3286 argument by using preprocessor conditionals.
3288 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3290 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3291 (scm_freopen): use RO string macros for filename and modes.

3305 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3308 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3310 support for byte vectors.
3312 * print.c (scm_iprin1): Limit number of vector elements printed
3313 according to pstate->length.
3315 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3320 * error.h: prototype for scm_error_scm.
3322 * error.c (scm_error_scm): new procedure, reimplements scm-error
3323 in C and uses scm_error.
3325 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3327 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3328 pointer to the Scheme variable read-hash-procedures and intern it
3329 in scm_init_read. Modify scm_read_hash_extend and
3330 scm_get_hash_procedure to use the pointer.
3332 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3334 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3335 (SCM_KEYWORD_STYLE): defined.
3337 * read.c (scm_read_opts): add a keywords option. This isn't a
3338 boolean option, in case someone wants to add support for DSSSL
3340 Setup scm_keyword_prefix symbol.
3341 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3343 I've left keyword support disabled by default, since it doesn't
3344 seem to break the module system and it gives R4RS standard behaviour.
3345 It can be reactivated with (read-set! keywords 'prefix).
3347 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3349 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3350 before constructing arbiter.
3352 * eval.c (scm_m_define): Bugfix: Check that the object is a
3353 closure before setting the procedure property!
3355 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3357 * ports.c: Removed `ungetc-char-ready?'.

3361 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3362 (idea from Mikael: make it a pair so scm_permanent object only
3364 (scm_read_hash_extend): don't call scm_permanent_object.
3365 (ideas from Mikael): if chr is already in the list, replace its
3366 procedure instead of appending it again. If proc is #f, remove
3368 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3370 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3372 * gdbint.c (gdb_read): update scm_lreadr usage.

3386 for extended # processing.
3387 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3388 scm_read_token): remove case_i, sharp arguments. Change callers.

3393 (SCM_CASE_INSENSITIVE_P): define.
3395 * read.c: add case-insensitive option to scm_read_opts.

3397 to determine whether to convert symbol case.
3398 (default_case_i): definition removed.
3399 * read.c (scm_read_token): if case_i, downcase ic before doing
3402 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3404 * configure.in: Added configuration option `guile-debug'.
3405 Configure with --enable-guile-debug if you want a bunch of extra
3406 functions used for debugging when developing Guile.
3408 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3410 * procs.c (make-cclo): New undocumented debugging procedure: Make
3411 compiled closure with internal procedure PROC and length LENGTH.
3412 Only compiled if GUILE_DEBUG is defined.
3414 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3416 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3418 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3420 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3421 with 3 or more args internally to the evaluator.
3423 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3425 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3426 with 3 or more args internally to the evaluator. This is mainly
3427 because we don't want to pass entry and exit points of the
3428 debug support twice, but it also seems to increase the speed of
3429 the evaluator for such calls (e. g. (+ 1 2 3)).
3431 * backtrace.c (scm_display_application): New procedure:
3432 display-application; Set fancy printing parameters individually
3433 for different types of display (backtrace, error, application).
3434 (These should of course be customizable!)
3436 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3437 clear the CHECK-flags.
3439 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3441 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3443 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3445 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3446 from pairs with a GLOC in the car.
3448 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3449 otherwise `symbol-hash' will behave badly.
3450 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3451 we get segmentation fault!
3453 * symbols.c: Added #include "weaks.h". New functions:
3454 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3455 moved to an extraneous library when we split libguile.)
3457 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3459 * filesys.c (scm_stat): stat now takes fport arguments too as
3460 documented in the manual.
3462 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3464 * debug.c (scm_single_step): Bugfix: Call continuation with
3465 scm_call_continuation instead of throwing to it.
3467 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3469 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3470 argument wasn't declared to be optional.
3472 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3474 * stime.c (scm_init_stime): Add feature "current-time".
3476 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3478 * throw.h: prototype for scm_exit_status.
3479 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3480 args to derive an exit status. Allows (quit) to work from a
3482 (scm_exit_status): new function.
3485 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3487 * eval.c (scm_deval): Removed some old code.
3488 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3490 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3493 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3496 * procs.c: Introduce the existent C function scm_thunk_p at the
3497 Scheme level as well.
3499 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3501 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3502 used from C to easily lookup the value of a symbol in the current
3505 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3507 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3508 scm_init_unif in this file. This will also fix a previous problem
3511 * configure.in: Added AM_MAINTAINER_MODE
3513 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3515 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3518 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3520 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3521 source files that are not always included in libguile but should
3522 have their dependencies calculated by automake. This variable is
3523 recognized by automake, no further magic is needed.
3524 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3525 to deal exclusively with *.lo files, as it seems. The *.o files
3526 are built automatically when the corresponding *.lo file gets
3529 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3531 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3534 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3536 * unif.c (scm_array_set_x): minor change to argument error checking.
3538 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3540 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3541 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3542 They should only be included in the library at configure.in's
3544 (libguile_la_LDADD): Include the appropriate .lo files here.
3545 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3546 so we know when to build them (and their .lo bretheren).
3547 * configure.in (LIBLOBJS): New substituted variable. We let
3548 configure decide which .o files to include in LIBOBJS, and then
3549 put the corresponding list of .lo files in LIBLOBJS. The latter
3550 is what we pass to libtool.
3551 * Makefile.in, configure: regenerated.
3553 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3555 * symbols.c (scm_sysintern0): New function. Contains the core of
3556 old scm_sysintern but doesn't take a second value argument.
3557 (scm_sysintern): Now uses scm_sysintern0.
3558 (scm_sysintern_no_module_lookup): Renamed to
3559 scm_sysintern0_no_module_lookup and doesn't take a second value
3560 argument any longer.
3562 * symbols.h (scm_sysintern0: Added declaration.
3564 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3565 scm_sysintern when interning option keys. Otherwise we risk
3566 destroying the values of already interned variables.
3568 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3569 scheme-level boolean (use SCM_NFALSEP).
3571 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3573 (scm_backtrace): New function. (C version of old function from
3574 boot-9.scm) Motivation: Make it possible to display backtraces
3575 without depending on boot-9.scm. (I'm uncertain if this
3576 motivation is good enough...)
3578 * root.h (scm_root_state): Add member the_last_stack_var.
3579 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3581 * root.c (mark_root): Mark scm_the_last_stack_var.
3583 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3586 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3588 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3589 1. mark_lazy_catch didn't mark the smob.
3590 2. Both functions above have standard variants:
3591 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3592 free_lazy_catch --> scm_free0.
3594 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3596 * throw.c (scm_internal_lazy_catch): New function.
3597 (scm_lazy_catch): Rewritten to use it.
3598 (scm_ithrow): Handle the new lazy catch representation.
3599 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3600 that doesn't have a jmpbuf is a lazy catch clause.
3601 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3602 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3603 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3605 (scm_init_throw): Register the new lazy-catch smob type.
3606 * throw.h (scm_internal_lazy_catch): decl for new function.
3608 * throw.c (scm_internal_catch): Doc fixes.
3610 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3611 configure.in. Including this might cause problems if applications
3612 that link against libguile include their own copies of alloca, but
3613 if they're using autoconf, they should be adding libguile to LIBS
3614 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3615 the copy in libguile, and things will be okay. (I think.)
3617 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3619 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3621 strop.h: move prototypes too.
3623 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3625 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3628 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3629 etc. I deleted them from filesys.c long ago, but didn't
3630 notice they were here too (although ineffective since
3631 sys/stat.h wasn't included).
3633 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3635 * eval.c: Don't define alloca in GCC case. gcc will automatically
3636 use __builtin_alloca if appropriate.
3638 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3640 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3641 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3642 that values of automatic variables are preserved. See comments
3643 for safe_setjmp for details.
3645 Change from Thomas Morgan:
3646 * variable.c: Include eq.h.
3647 (var_equal): New function.
3648 (variable_smob): Use var_equal as the discriminator for variables.
3650 * throw.c (s_throw): Remove extraneous declaration.
3652 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3653 * eval.c: Add necessary CPP cruft to support that.
3654 * configure, Makefile.in, scmconfig.h.in: regenerated.
3656 Change from Thomas Morgan:
3657 * procprop.c (scm_procedure_properties): Convert the Scheme
3658 boolean returned by scm_procedure_p into a C boolean before using
3659 it as a condition for SCM_ASSERT.
3660 (scm_procedure_property): Likewise.
3662 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3663 indications of Unixness.
3666 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3668 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3670 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3672 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3673 "unknown # object" error messages.
3675 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3676 (scm_i_index) and declare it static. Add a 'direction' argument
3677 to indicate what way the search should go.
3678 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3680 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3681 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3683 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3685 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3687 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3688 to avoid clash with various scsh forks.
3690 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3692 The following two changes (ramap.c, throw.c) are motivated by the
3693 apparent unportability of forward declarations of static arrays of
3694 the form `static foo bar[];'.
3696 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3697 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3699 * throw.c (scm_throw): Moved above scm_ithrow.
3701 * options.h: Removed the extern declarations of scm_yes_sym and
3702 scm_no_sym since these are static.
3704 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3706 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3708 * Makefile.am: remove AWK=@AWK@.
3709 Add a rule for generating errnos.list.
3710 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3712 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3713 don't extract errnos, just set a variable (avoids the
3714 need to recompile error.c just because configure is run.)
3716 * unif.h: update prototypes.
3717 * unif.c (scm_uniform_array_read,write): change the offset and
3718 length arguments to start and end, for consistency.
3720 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3722 * ioext.h: update prototypes.
3723 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3724 scm_read_line_x, it's a more general procedure using an
3725 interface from scsh. read-line and read-line! are now defined
3727 Note that the new read-line trims the terminator
3728 by default, previously it was appended to the returned string. An
3729 optional argument specifies how to process the terminator (scsh
3730 compatible). For the old behaviour: (read-line port 'concat).
3731 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3732 returns a pair, but is converted to multiple values if the scsh
3735 socket.h: update prototypes.
3736 * socket.c (scm_recvfrom): for consistency with other procedures,
3737 take start and end as separate optional arguments.
3738 (scm_recv, scm_recvfrom): don't allow the second argument
3739 to be a size, only a buffer. Change the scheme names to
3740 recv! and recvfrom!. Don't return the buffer.
3742 * ioext.h, posix.h: move prototypes too.
3743 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3744 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3745 "read.h" and "unif.h".
3746 * ioext.c: include "chars.h"
3748 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3750 * dynl.c: The dynamic linking and module registration functions
3751 are now defined even when dynamic linking is not available for the
3752 host system. Some of their functionality can be done without
3753 dynamic linking; when it's really needed, they throw errors.
3755 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3757 * configure.in: Only define DYNAMIC_LINKING when one of the system
3758 dependent functions is detected.
3759 * dynl.c (scm_dynamic_func): New function to get the address of a
3760 function in a dynamic object.
3761 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3762 produced by scm_dynamic_func as the thing to call.
3764 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3766 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3767 (scm_register_module_xxx, scm_registered_modules,
3768 scm_clear_registered_modules): New functions.
3770 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3772 * symbols.c (scm_sysintern): Renamed to
3773 scm_sysintern_no_module_lookup.
3774 (scm_sysintern): New function to take the place of the old
3775 scm_sysintern. It uses the current toplevel lookup closure to give
3776 the symbol its value. This is a temporary hack to put packages
3777 like gtcltk into their own module.
3778 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3779 us whether `scm_top_level_lookup_closure_var' has been initialized
3781 * eval.c (scm_init_eval): Set it.
3783 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3785 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3786 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3788 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3790 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3791 scm_sys_dup): deleted: FD capability will be added to other
3793 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3794 scm_fd_free, fd_smob, scm_intern_fd.
3795 (scm_open): renamed from scm_sys_open. Return a port instead of
3796 an FD object. Make the mode argument optional.
3797 (scm_sys_create): deleted, it's just a special case of open.
3798 (scm_init_filesys): move interning of constants O_CREAT etc.,
3799 here (were previously using SCM_CONST_LONG macro).
3800 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3802 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3803 include "fports.h" and <stdio.h>
3804 (scm_stat, scm_select): don't support FD objects.
3806 * error.h: adjust scm_syserror_msg prototype.
3807 * error.c (scm_syserror_msg): take an extra argument for errno.
3808 Using the global value didn't always work, since it could be
3809 reset by procedure calls in the message or args arguments.
3811 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3812 I don't understand why the check was there (and what about the
3815 * strop.c (scm_string_copy): allow shared substrings to be copied.
3817 * unif.h: corresponding change to prototypes.
3818 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3819 recognize two new optional arguments: offset and length. Allow
3820 the port argument to be an integer (file descriptor, for scsh).
3821 Include <unistd.h> for "read" prototype.
3823 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3825 * socket.c: don't include filesys.h.
3827 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3829 * Makefile.am: add AWK=@AWK@ (?)
3831 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3833 Add a rule to generate errnos.c from errnos.
3834 * error.c (scm_init_error): include errnos.c.
3835 * errnos_cnvt.awk: new file, converts the list of errno codes to
3837 * errnos_get.c: new file.
3838 * errnos.default: new file, contains errnos to try if they can't
3839 be extracted from errno.h.
3840 * configure.in: if using GCC, try and extract errno codes from
3844 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3846 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3847 * Makefile.am: Made libguile into a libtool library.
3848 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3849 Set libtool_libs to indicate that libguile is a libtool library.
3850 See guile/ChangeLog for details.
3851 * .cvsignore: ignore "*.lo", the libtool library objects.
3853 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3855 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3856 use htons in getservbyport argument.
3858 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3860 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3861 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3864 * objprop.c (scm_object_property): No need to take the CDR of the
3865 value returned by scm_object_properties, since Aug 20 change.
3867 * configure.in: When checking for struct linger, #include
3868 <sys/types.h> as well as <sys/socket.h>. I've never known
3869 <sys/types.h> to cause any portability problems, and Solaris's
3870 <sys/socket.h> needs it.
3871 * configure: Rebuilt.
3873 I think the Sun compiler has chosen a perverse way to interpret
3874 ANSI declarations combined with K&R definitions. We'll
3875 appease it a little bit. But when it invades France, we fight.
3876 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3877 * print.h (scm_iprlist): Here too.
3878 * numbers.c (scm_divbigdig): Change definition to match
3879 declaration in numbers.h.
3880 * unif.c (scm_makflo): Change definition to match declaration in
3883 * init.c (scm_boot_guile): Don't return the value of
3884 scm_boot_guile_1. This function doesn't return a value;
3885 scm_boot_guile_1 doesn't return a value (or return at all).
3887 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3890 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3891 compile. I have a feeling this function is a bad idea anyway ---
3892 one should always test for features, not systems.
3894 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3895 semicolons. Only pure luck kept this from being noticed earlier.
3897 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3899 * socket.c (scm_recvfrom): Added missing semicolon.
3901 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3903 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3904 the buffer and start and end positions for scsh networking
3907 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3909 * configure.in: Revert previous change to this file; the problem
3910 is due to transient automake weirdness.
3911 * configure: Rebuilt.
3913 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3914 PLUGIN/guile.libs. configure generates the latter from the former.
3915 * Makefile.in: Rebuilt.
3917 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3918 need this if we install scripts, like guile-snarf.
3919 * configure: Rebuilt.
3921 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3923 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3925 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3927 * socket.c (scm_addr_vector): fix faulty scm_listify.
3929 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3931 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3932 style block comment is no longer considered an error.
3934 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3936 * PLUGIN/guile.libs.in: New file.
3937 * PLUGIN/guile.libs: Removed from repository.
3938 * configure.in: Create PLUGIN/guile.libs from
3939 PLUGIN/guile.libs.in. This is for including additonal libraries
3940 needed for dynamic linking.
3941 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3942 instead of PLUGIN/guile.libs.
3944 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3946 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3948 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3949 occurrences of the given element from the list, not just the
3950 first. This is how the Emacs Lisp functions behave, how the
3951 analogous Common Lisp functions behave, and (I believe) how the
3952 older Maclisp functions worked. I realize that this change may
3953 break code, but it seemed better to break it before the Guile
3956 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3957 Their prototypes were already present in gc.h, but they weren't
3959 (scm_init_storage): Initialize scm_protects.
3960 * root.c (scm_protects): New element of scm_sys_protects.
3962 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3964 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3966 * libguile.h: Added #include "libguile/net_db.h".
3968 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3969 30 change. That file is only meant for communication between the
3970 configuration process and load.c. If code linked against libguile
3971 wants to get at the paths mentioned in libpath.h, it can call
3972 functions declared in load.h.
3974 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3976 * libguile.h: Removed #include "libguile/fdsocket.h"
3978 * net_db.c: Added #include <sys/socket.h>.
3980 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3982 * filesys.c (scm_input_waiting_p): use select in preference to
3983 FIONREAD, since the latter doesn't detect EOF.
3984 Throw error if neither select nor FIONREAD available.
3986 * socket.c (scm_connect): take a port, not a fd object.
3987 (scm_fill_sockaddr): throw an error if fam is not recognised.
3988 (scm_bind): use scm_fill_sockaddr.
3989 (scm_listen): take a port, not a fd object.
3990 (scm_accept): take and return a port. return #f in the car if
3991 address can't be got
3992 (scm_sock_fd_to_port): new procedure.
3993 (scm_socket): use scm_sock_fd_to_port.
3994 (scm_addr_vector): throw error if unrecognised address type.
3995 take an extra argument with the calling procedure name.
3996 (scm_getsockname): take a port. return #f if address can't be got.
3997 (scm_getpeername): take a port. return #f if address can't be got.
3998 (scm_recvfrom): take a port. return #f for address component if can't
4000 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4001 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4003 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4005 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4006 use separate data pointers, to allow them to be designed
4007 independently and reused.
4008 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4009 Renamed from catch_body, catch_handler, and uncaught_throw; made
4011 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4013 (scm_catch): Use the above.
4014 (scm_throw): Don't bother printing a message for an uncaught
4015 throw; we establish a default handler in init.
4016 * throw.h (scm_internal_catch): Prototype updated.
4017 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4019 (struct scm_body_thunk_data): New structure, used as data
4020 argument to scm_body_thunk.
4021 * init.c (struct main_func_closure): New structure, packaging up
4022 the data to pass to the user's main function.
4023 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4024 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4025 scm_internal_catch to establish a catch-all handler, using
4026 scm_handle_by_message. This replaces the special-case code in
4028 (invoke_main_func): Body function for scm_internal_catch; invoke
4029 the user's main function, using the main_func_closure pointer to
4030 decide what to pass it.
4031 * root.c (struct cwdr_body_data): Remove handler_proc member.
4032 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4033 (cwdr_handler): Removed.
4035 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4037 * socket.h (SCM_P): update bind prototype.
4038 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4039 include "feature.h".
4040 (scm_socket): return a port, not a file descriptor object.
4041 include "fports.h" and <unistd.h>
4042 (scm_bind): take a port, not a file descriptor object.
4043 take an extra argument for address args.
4045 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4046 INADDR_NONE, INADDR_LOOPBACK.
4048 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4050 * init.c: include net_db.h and not fdsocket.h.
4051 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4053 * Makefile.am: corresponding changes.
4054 * socket.h: renamed from fdsocket.h, fix names.
4055 * net_db.h: renamed from socket.h, fix names.
4056 * socket.c: renamed from fdsocket.c.
4057 remove _sys from procedure names.
4058 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4059 add "socket" to features list.
4060 * net_db.c: renamed from socket.c.
4061 remove _sys from procedure names.
4062 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4063 add "net-db" to features list.
4064 include "net_db.h". don't include <sys/socket.h> or
4067 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4069 * tags.h (scm_tags): Removed comma at end of last enumerator.
4071 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4073 Don't use GCC extensions to allocate space for debugging frames.
4074 (Here he goes again! Why do we put up with this?!)
4075 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4076 an scm_debug_info structure, not an in-line array of them. Add
4077 'info' member, to say how many vect elements we've used, for eval
4079 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4080 a new variable debug_info_end to mark the end of vect, instead of
4081 the address of the 'info' pointer itself.
4082 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4083 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4084 (SCM_APPLY): Explicitly allocate space for debug.vect.
4085 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4086 * stacks.c: Adjusted for new debug frame structure.
4087 (RELOC_INFO, RELOC_FRAME): New macros.
4088 (stack_depth, read_frames): Use them, and new scm_debug_frame
4089 element 'info', instead of magically knowing that eval frames have
4090 an info pointer sitting after vect.
4091 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4093 (scm_init_stacks): Formatting tweaks.
4095 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4097 Give GCC more control flow information, so it can be sure that
4098 variables aren't used uninitialized.
4099 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4100 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4101 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4102 scm_misc_error): Tell GCC that these functions never return.
4103 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4104 out the field type, call abort if SCM_ASSERT returns, to placate
4106 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4107 scm_wta ever returns. We can't handle this case anyway, and this
4108 gives the optimizer more information.
4109 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4110 scm_wta ever returns.
4112 In some cases, the code is fine, but GCC isn't smart enough to
4113 figure that out; this usually happens when one variable is only
4114 initialized and used when a particular condition holds true, and
4115 we know that condition will never change within a given invocation
4116 of the function. In this case, we simply initialize the variables
4117 to placate the compiler, hopefully to a value which will cause a
4118 crash if it is ever actually used.
4119 * print.c (scm_iprin1): Initialize mw_pos.
4120 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4121 * throw.c (scm_ithrow): Initialize dynpair.
4122 * unif.c (scm_uniform_vector_ref): Initialize cra.
4123 * struct.c (init_struct): Initialize prot.
4124 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4126 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4127 if EXPR contains no expressions.
4129 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4131 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4132 cause an infinite loop (???). So much for the algebraic
4133 equivalency of variable-sized arrays and alloca...
4135 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4137 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4138 a SCM boolean, not a C boolean.
4140 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4142 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4143 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4144 rules for raising scm_mtrigger. Previously, unfortunate but not
4145 unlikely circumstances could result in almost constant invokation
4146 of the gc. Now, this situations should be less likely, but they
4147 are not prevented completely.
4149 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4151 * numbers.c (scm_fuck): Procedure removed; looks like old test
4153 * numbers.h: Prototype removed.
4155 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4157 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4158 array to a pointer, to match my Nov 21 change in eval.c.
4160 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4162 * libguile.h: Added #include "libguile/backtrace.h", #include
4163 "libguile/stacks.h".
4165 * strings.c (scm_string scm_make_string scm_string_ref
4166 scm_string_set_x scm_string_equal_p scm_string_append):
4167 Bugfix according to scm patch from Aubrey Jaffer:
4168 Corrected long-standing
4169 (not (eqv? (integer->char 128)
4170 (string-ref (make-string 1 (integer->char 128)) 0)))
4171 bug found by John Kozak <jk@noontide.demon.co.uk>.
4173 * strports.c, strports.h: Make scm_eval_0str return the value of
4174 the last expression evaluated (previously, it returned void).
4176 * strports.c, strports.h: New function: scm_read_0str. Does what
4179 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4181 * simpos.c (scm_getenv): return #f if string can't be found in the
4182 environment instead of throwing an exception, for compatibility
4183 with numerous other systems.
4185 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4187 * Makefile.am (.c.x): Use guile-snarf.
4188 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4190 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4192 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4194 * backtrace.c (scm_display_error_message): Made non-static, and
4195 renamed from display_error_message.
4196 * backtrace.h (scm_display_error_message): Added extern decl.
4197 * throw.c (uncaught_throw): Use it to display the error message.
4199 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4201 * inet_aton.c: Use #if 0, not #ifdef 0.
4203 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4205 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4206 to convert the returned value.
4207 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4208 the offset argument.
4210 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4212 Add new interface to catch/throw, usable from C as well as
4214 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4215 (scm_internal_catch): New function, replaces...
4216 (scm_catch_apply): Deleted.
4217 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4218 mechanism which is a bit more code, but can be used nicely from C
4219 and implement the Scheme semantics as well.
4220 (scm_internal_catch): This is the replacement; it's named after
4221 the analogous function in Emacs.
4222 (scm_catch): Reimplemented in terms of the above.
4223 (struct catch_body_data, catch_body, catch_handler): New
4224 functions, used by scm_catch.
4225 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4226 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4227 support for new cwdr.
4229 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4232 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4234 * acconfig.h: Added DYNAMIC_LINKING symbol.
4235 * configure.in: Add option and checks for dynamic linking.
4236 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4237 dynl.h: New files for dynamic linking support.
4238 * Makefile.am (libguile_a_SOURCES):
4240 (modinclude_HEADERS): Added "dynl.h".
4241 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4243 * init.c (scm_boot_guile_1): Call
4244 scm_init_dynamic_linking to initialize dynamic linking support.
4246 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4248 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4249 (as we Schemers say). It needs to be global, so that I can tweak
4250 it for the proper operation of unexec.
4251 (scm_boot_guile_1_live): New variable, see above.
4253 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4255 * guile-snarf.sh: Removed.
4256 * PLUGIN/guile.libs: Added dependency for -lm.
4257 * acinclude.m4: Renamed from aclocal.m4.
4258 * PLUGIN/greet: Removed.
4259 * Makefile.am, aclocal.m4: New files.
4260 * configure.in: Updated for Automake.
4262 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4264 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4265 and not top_level_lookup_thunk_var.
4267 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4269 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4271 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4273 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4274 Scheme function, instead of syntax. Single argument is now a
4277 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4279 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4280 scm_ra_divide): Properly terminate statements passed as arguments
4281 to IVDEP macros. (Thanks to Bernard Urban.)
4283 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4284 with non-constant sizes. (Thanks to Bernard Urban.)
4286 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4288 It's an "eval closure", not an "eval thunk." A thunk is a
4289 function of no arguments.
4290 * root.h (struct scm_root_state): Renamed
4291 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4292 (scm_top_level_lookup_closure_var): Renamed from
4293 scm_top_level_lookup_thunk_var.
4294 * root.c (mark_root): Uses changed.
4295 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4296 * init.c (scm_start_stack): Uses changed.
4297 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4298 Change scheme-visible name to *top-level-lookup-closure* from
4299 *top-level-lookup-thunk*.
4301 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4303 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4304 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4306 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4308 * gc.c (struct scm_heap_seg_data): Doc fixes.
4310 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4311 sweeping. Then, prepend each segment's free cells to its
4312 freelist, rather than wiping out the old value. (Thanks to Marius
4315 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4316 scm_check_freelist, scm_debug_newcell): New functions and
4317 variables, for debugging freelist problems.
4318 * pairs.h (SCM_NEWCELL): New debugging version added.
4319 * gc.h (scm_debug_newcell): Added extern declaration, used by
4320 debugging version of SCM_NEWCELL.
4322 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4324 On some systems <libc.h> conflicts with <unistd.h>, and should not
4325 be #included at all.
4326 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4327 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4328 * configure.in: Call it.
4329 * posix.c, filesys.c: Use its results to decide whether or not to
4331 * configure, scmconfig.h.in: Rebuilt with autoconf and
4334 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4336 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4337 pointer to the stdio stream before calling scm_setbuf0, so the
4338 latter will be able to retrieve it. I'm surprised this didn't
4339 segfault earlier. (Thanks to Christopher Lee.)
4341 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4343 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4346 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4348 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4349 number of stack narrowing specifier pairs. The first specifier in
4350 a pair controls inner border, the second the outer border. A
4351 number means cut that number of frames, a procedure object means
4352 cut until that object is found in operator position in a frame.
4354 * root.c (cwdr): Bugfix.
4356 * read.c: Recording of positions disabled by default.
4358 * procs.c (scm_closure_p): New function.
4360 * posix.c (scm_tmpnam): New function.
4362 * load.c: Added #include "throw.h".
4363 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4366 * load.c, load.h (scm_read_and_eval_x): New function.
4368 * eval.c: Renamed debug option "deval" to "debug".
4370 (scm_eval_x): `eval!' is no longer accessible from the scheme
4371 level. Motivation: We can't allow operations which introduce
4372 glocs into the scheme level. Guile's type system can't handle
4373 these as data. Use `eval' or `read-and-eval!' as replacement.
4375 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4376 SCM_CONSP since this is a macro!; Set vframe.prev to
4377 scm_last_debug_frame instead of 0. In this way we can look
4378 "above" the virtual start stack frame if we wish.
4379 (scm_debug_hang): New function: Useful for debugging Guile in
4380 certain tricky situations. Will probably be removed later...
4382 * debug.h: Changed semantics of debug option "backtrace". This
4383 option now only indicates whether we want automatic backtrace at
4386 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4388 * ports.c: #include "filesys.h"
4389 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4391 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4392 Motivation: This is system specific code which is related to file
4393 I/O. It also may use select. Added code by Gary Houston to
4394 detect presence of character in stdio buffers.
4396 * libguile.h: #include "libguile/libpath.h"
4398 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4399 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4400 SCM_SITE_DIR; Install libpath.h among the other include files.
4402 * load.c, load.h (scm_sys_package_data_dir): New function.
4404 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4406 * stacks.h: Bugfix: Don't use tail-array length field as stack
4407 length field! This screwed GC.
4409 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4411 * _scm.h: Added #ifndef around definition of macros min and max.
4413 * __scm.h: Added hooks for threads to plugin to in ints protection
4414 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4415 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4416 the main code in these macros duplicated and spread over multiple
4417 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4418 SCM_THREAD_SWITCHING_CODE.
4420 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4422 * snarf.h: New file.
4423 * guile-snarf.sh: New file.
4424 * Makefile.in (inner_h_files): Added snarf.h
4425 (ancillary, install, uninstall, distclean): Added actions for
4427 (.c.x): Use guile-snarf.
4428 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4429 (gen_c_files): Note that these depend on guile-snarf.
4430 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4431 now in "snarf.h". Added #include "snarf.h" to get them.
4432 * libguile.h: Added #include "snarf.h".
4433 (Patches applied and tweaked by Jim Blandy.)
4435 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4437 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4438 standards suggest against providing prototypes for system
4439 functions. Thanks to Greg Troxel.
4441 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4443 * strports.c (scm_eval_0str): New function.
4444 #include "read.h", to get prototype for scm_read.
4445 * Makefile.in (strports.o): Update dependencies.
4446 * strports.h: New prototype.
4448 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4449 scheme name from "int?" to "integer?". It seems to do the job.
4450 * numbers.h: Rename prototype too.
4451 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4454 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4455 scm_num_eq_p): Rename these according to R4RS conventions: call
4456 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4457 to making libguile R4RS compliant without ice-9...
4459 * load.c (scm_sys_search_load_path): Search for files under all
4460 extensions listed in the %load-extensions variable. If FILENAME
4461 is absolute, return it unchanged, without searching the load path.
4462 (scm_loc_load_extensions): New variable, pointing to
4463 %load-extensions' value cell.
4464 (scm_init_load): Initialize it, and the value it points to.
4465 (scm_primitive_load_path): Improve error reporting.
4467 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4468 of new Scheme variable %load-hook.
4469 (scm_primitive_load): Apply %load-hook to filename.
4471 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4473 * configure.in: add tests for figuring out whether buffered data
4474 is available in a FILE structure, which is needed by char-ready.
4476 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4479 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4480 exceptions using misc_error instead of syserror. It seems a bit
4481 odd to throw an exception if a string can't be found in the
4482 environment, but it's consistent with open-file, stat etc.
4483 (simpos.h): remove sys_ from getenv.
4485 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4486 occurs, throw an error instead of returning errno. Return value
4488 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4490 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4492 * filesys.c (scm_stat2scm): derive file type and permissions from
4493 the stat mode and append them to the returned vector.
4494 There isn't much overhead in doing this and it avoids the need to
4495 work with S_IRUSR et al. in Scheme.
4496 Define symbols scm_sym_regular etc.
4497 (scm_init_filesys): don't intern S_IRUSR etc.
4499 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4500 and s_primitive_load_path.
4502 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4504 * error.h: don't declare error symbols. prototype for scm_misc_error.
4506 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4509 * error.c: use SCM_SYMBOL to set up error keys.
4510 scm_misc_error: new procedure.
4512 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4514 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4515 between `#!' and `!#' is ignored.
4516 (skip_scsh_block_comment): New function.
4518 * feature.c (scm_set_program_arguments): New argument, FIRST.
4519 * feature.h: Update prototype.
4520 * init.c (scm_boot_guile_1): Pass new argument to
4521 scm_set_program_arguments.
4523 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4525 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4526 (scm_boot_guile): Call scm_set_program_arguments here, later than
4527 the old initialization.
4529 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4530 initialization procedure.
4531 - Delete in, out, err arguments; there are other perfectly good
4532 ways to override these when desired.
4533 - Delete result argument; this function shouldn't ever return.
4534 - Rename init_func argument to main_func, for less confusion.
4535 - Delete boot_cmd argument; main_func is more general.
4536 -Add 'closure' argument, to help people pass data to main_func
4537 without resorting to global variables.
4538 - Abort if reentered; don't bother returning an error code.
4539 - Call scm_init_standard_ports to set up the default/current
4540 standard ports; no need to pass them to scm_start_stack.
4541 - Remove code to evaluate the boot_cmd, and start the repl; let
4542 the user do something like that in main_func if they want.
4543 - Remove code to package up a return value; main_func can do any
4545 - Call exit (0), instead of returning.
4546 (scm_start_stack): Don't initialize the I/O ports here; that's
4547 weird. Delete in, out, err arguments. Move guts to
4548 scm_init_standard_ports, scm_stdio_to_port.
4549 (scm_init_standard_ports): New function, to set up current and
4550 default standard ports.
4551 (scm_start_stack, scm_restart_stack): Make these static.
4552 * init.h (scm_boot_guile): Adjust declaration.
4553 (scm_start_stack, scm_restart_stack): Remove externally
4554 visible declarations for these.
4555 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4557 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4558 written out several times in scm_start_stack.
4559 * fports.h: New declaration for the above.
4561 * feature.c (scm_set_program_arguments): New function.
4562 * feature.h: New declaration for the above.
4564 * ports.c: Formatting tweak.
4566 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4568 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4569 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4570 for obtaining the address of a car or cdr field. Motivation:
4571 &SCM_CXR make assumptions about the internal structure of the
4574 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4575 Motivation: see SCM_CXRLOC.
4577 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4578 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4579 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4580 Motivation: Safer use. Some other macros are defined in terms of
4581 these operations. If these are defined using the SCM_SETCXR
4582 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4583 to inefficiency and an <e1> with side-effects could potentially
4584 break. Also, these particular operations are heavily utilized in
4585 the garbage collector. In unoptimized code there will be a
4588 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4589 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4590 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4591 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4592 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4593 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4594 vports.c: Cleaned up use of pairs: Don't make any special
4595 assumptions about the internal structure of selectors and
4596 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4597 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4598 (Among other things, this change makes it easier to build Guile
4599 with certain compilers which have problems with casted lvalues.)
4601 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4603 * stacks.c: Improve selection of relevant stack frames when making
4604 a stack object. Introduce one level of indirection in the stack
4605 object to make it possible to "narrow" to a certain region of the
4606 stack. This facilitates making use of more clever algorithms (not
4607 implemented) for selecting relevant frames and gives a cleaner
4608 design since selection of frames can be done independently of
4609 extraction of frames from the real stack.
4610 (scm_stack_id): Also take #t as argument which means look at
4613 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4614 Turn n_tail into an integer directly representing current number
4615 of frames in stack. Add field tail.
4617 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4619 * debug.c (scm_make_memoized): Made it available at scheme level.
4620 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4621 SCM_NIMP before applying heavier predicates in argument checking.
4622 (scm_local_eval): Also take memoized object as argument.
4624 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4625 aren't created with zero length, but should such a strange
4626 creature suddenly turn up...
4628 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4630 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4631 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4633 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4635 * variable.c (scm_make_variable): Make the name hint optional, as
4637 (anonymous_variable_sym): Renamed from variable_sym. All uses
4640 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4641 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4642 of scm_primitive_load_path was also changed to
4643 "primitive-load-path", from "%try-load-path". Callers changed.
4644 We'd like to respect the convention that a function named
4645 "try-mumble" should behave just like the function called "mumble",
4646 but return #f instead of signalling some error.
4647 * load.h: Rename prototypes.
4649 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4651 * print.c (make_print_state, grow_print_state), print.h: Modified
4652 the print state representation: Don't use a tail array for
4653 recording of circular references. Resizing of the print state
4654 structure invalidates the print state pointer. To avoid passing
4655 around an indirect print state reference to all printing
4656 functions, we instead let the print state reference a resizable
4659 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4661 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4662 Don't crash when passed an improper list terminated by a
4663 non-immediate value.
4665 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4667 Allocate data for structures on an eight-byte boundary, as
4668 required by the tagging system.
4669 * struct.c (alloc_struct): New function.
4670 (scm_make_struct, scm_make_vtable_vtable): Call it.
4671 * struct.h (scm_struct_n_extra_words): Bump to 3.
4672 (scm_struct_i_ptr): New "field".
4673 * gc.c (scm_gc_sweep): When we need to free the data, use the
4674 information stored by alloc_struct to find the beginning of the
4675 block allocated to the structure, so we can free it.
4677 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4679 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4682 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4683 (scm_debug_info): New member: id.
4685 * stacks.c: Stacks are now represented as structs; Stacks have an
4686 id given to them by `start-stack'.
4687 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4689 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4690 Changed stack representation.
4692 * debug.c (scm_procedure_name): Try procedure property `name' for
4693 compiled closures aswell.
4695 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4697 * eval.c: scm_i_name moved to gsubr.c
4698 (scm_m_define): Record names of all kinds of procedure
4699 objects. (Earlier, only closures were recorded.)
4701 * procprop.h: Added declaration of scm_i_name.
4703 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4704 (scm_make_gsubr): Record names of compiled closures.
4706 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4708 * debug.c, debug.h: Removed obsolete code.
4710 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4711 stacks.c: Renamed regs --> scm_contregs.
4713 * print.c (scm_free_print_state): Cleanup print state before
4714 returning it to pool. It is better to do it here than in
4715 scm_prin1 since scm_prin1 is called often.
4717 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4718 s_set_source_property_x): Check that first argument is a pair or a
4721 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4722 scm_i_line, scm_i_column and scm_i_breakpoint global.
4724 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4725 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4728 * debug.h: Added debug object smob declaration and macro
4731 * configure.in: Build with backtrace.o and stacks.o if debug
4734 * Makefile.in: Added entries for new files: backtrace.c,
4735 backtrace.h, stacks.c and stacks.h.
4737 * symbols.c (scm_sym2ovcell): Fixed documentation.
4739 * _scm.h (min, max): Added.
4741 * async.c: Moved `min' macro to _scm.h.
4743 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4744 SCM_BACKTRACE_INDENT.
4746 * eval.c: Added new debug options `maxdepth' and `indent'.
4748 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4750 * print.h: Added selector SCM_PRINT_STATE.
4752 * print.c: New functions: scm_make_print_state,
4753 scm_free_print_state.
4755 * print.h: Added declarations for scm_make_print_state,
4756 scm_free_print_state.
4758 * debug.c (scm_m_start_stack): New acro.
4760 * debug.h: Small cleanup.
4762 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4765 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4790 More prototype-related changes from Marius Vollmer:
4791 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4792 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4793 * ports.h (ptobfuns): Added prototypes. This means some casting in
4795 * fports.c: Added casts for initializations, since the functions
4796 are defined to take FILE * as their stream argument, not SCM.
4797 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4798 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4799 to `char *str_data' to conform to prototype.

4803 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4805 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4807 * stime.c, stime.h: use SCM_P method.
4809 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4811 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4812 be given at least two arguments. Insist that lst's last element
4813 be a list, but don't make any requirements of its predecessors.
4815 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4817 * eval.c (scm_nconc2last): Revert last change; there seems to be
4818 other stuff going on here.
4820 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4822 * eval.c (scm_nconc2last): Make sure that each element of lst
4823 (which is a list of argument lists, except for the tail) is a
4824 proper list, i.e., finite and terminated by '().
4826 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4828 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4831 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4832 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4835 * vectors.c (scm_make_vector): Fill vectors with the undefined
4836 value, to help make Guile Scheme code more portable to other
4839 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4840 * symbols.h, tags.h: Doc fixes.
4842 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4844 * async.c (scm_take_signal): Doc fixes.
4846 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4848 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4849 want to subtract it from the modulus; we just want to leave it
4852 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4854 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4857 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4859 * throw.c (scm_catch_apply): Finished implementation of
4862 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4864 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4866 (scm_init_filesys): set "i/o-extensions" feature.
4869 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4871 * Makefile.in (root.o): Correct dependencies.
4873 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4875 * Makefile.in: Added dependency entry for root.o.
4877 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4878 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4880 * init.c (scm_start_stack): Set initial root continuation number
4883 * procs.c: New function: scm_thunk_p.
4885 * procs.h: Added declarations of scm_thunk_p.
4887 * root.c: Renamed `call-with-new-root' -->
4888 `call-with-dynamic-root'.
4889 (cwdr): Removed allocation of new root state. This should be done
4890 separately by use of scm_make_root.
4891 (scm_apply_with_dynamic_root): New function: Does what it
4892 sounds like. Needed when spawning threads.
4894 * root.h: Added member last_debug_frame to root state.
4895 Added #include "libguile/debug.h"
4897 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4898 arguments. The motivation is that code in root.c needs catch
4899 functionality, and we want to avoid code duplication.
4900 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4901 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4902 handlers that run without popping the stack into the dynwind
4905 * throw.h: Added prototypes for scm_catch_apply and
4908 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4910 * root.h (scm_root, scm_set_root): Decouple thread support details
4911 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4912 SCM_SET_THREAD_LOCAL_DATA.
4914 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4915 and tortoise scanning loop.
4917 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4919 * Makefile.in: Rebuild dependencies.
4921 * libguile.h: #include "libguile/print.h" before "smob.h", since
4922 the latter uses the print_state structure.
4924 * throw.c (scm_ithrow): Use the correct variable when checking to
4925 see if a given element of scm_dynwinds is a valid catch.
4927 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4928 structure, abort; don't just silently ignore the garbage.
4930 * _scm.h: #include "print.h" here, since it seems to be used just
4932 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4933 strports.c, unif.h: Don't #include "print.h".
4935 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4937 * feature.h (scm_loc_features): Removed external declaration.
4938 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4940 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4942 * feature.c (scm_init_feature): Added threads feature (needs to be
4943 initialized here, since features doesn't exist when
4944 scm_init_threads is called).
4946 * libguile.h: Added #include "libguile/../threads/threads.h".
4947 (This is a kludge to get thread support working. This should be
4950 * configure.in, acconfig.h: Added flags for thread support.
4952 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4955 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4956 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4959 * _scm.h: Added conditional #include "threads.h"
4961 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4962 SCM_THREADS_SWITCHING_CODE.
4964 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4965 allocate the basic dynamic root object.
4966 (scm_boot_guile): Added call to scm_init_root.
4968 * root.c, root.h: Added root smob.
4969 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4970 functions: Implements dynamic roots mostly according to spec in
4971 SCM manual. Main difference is that the second argument is a
4972 throw handler rather than an error "thunk".
4974 * root.h: Added declaration of scm_init_root.
4976 * root.c: Added #include "genio.h", #include "smob.h", #include
4977 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4979 (scm_init_root): Added #include "root.x".
4981 * throw.c: Added #include "stackchk.h"
4982 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4983 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4984 can be used in scm_call_with_new_root; Added reenabling of stack
4985 checking when catching a throw.
4987 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4989 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4991 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4992 element is not found, as per R4RS.
4994 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4996 * list.c: Doc fixes throughout.
4998 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5000 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5001 declare the char * to be const. Avoids a warning in rgx.c.
5003 * ports.h: spelling fix.
5005 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5008 * load.c (scm_sys_try_load_path): throw an error if file not found
5009 (like it says it in NEWS).
5011 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5013 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5014 PROPS slot to '(), not #f; it's an empty alist.
5016 * throw.h, throw.c: Use SCM_P instead of #if hair.
5018 Remove special support for uncaught throws; see throw.c for
5020 * throw.c (uncaught_throw): New function.
5021 (scm_ithrow): Call uncaught_throw if we don't find a throw
5022 target; don't mess with scm_bad_throw_vcell.
5023 (scm_bad_throw_vcell): Variable deleted.
5024 (scm_init_throw): Don't initialize it.
5026 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5029 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5031 * numbers.c (scm_istr2int): If the number is short (as most
5032 numbers are), just call scm_small_istr2int to deal with it.
5033 (scm_small_istr2int): New function, created by un-#ifdefing the
5034 non-bignum version of scm_istr2int and renaming it.
5036 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5038 * load.c (scm_sys_try_load): don't check whether value returned
5039 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5040 Change the Scheme name from %try-load to primitive-load.
5042 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5043 Can avoid passing a message, allowing it to be derived in the
5044 error handler (e.g., if we want to throw to the key both from
5047 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5049 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5050 references now have a new appearance which is more compact and
5051 also gives a clue about what the target of the reference is.
5052 By setting parameters in the print state, more fancy printing can
5053 be achieved. This is used by the (not yet commited) backtrace
5056 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5058 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5061 * print.c: Added #include "struct.h". Removed function
5064 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5065 scm_iprin1. Removed prototype for scm_prlist.
5067 * arbiters.c (prinarb),
5068 async.c (print_async),
5069 debug.c (prindebugobj, prinmemoized),
5070 eval.c (prinprom, prinmacro),
5071 filesys.c (scm_fd_print, scm_dir_print),
5073 mallocs.c (prinmalloc),
5074 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5075 smob.h (scm_smobfuns),
5076 srcprop.c (prinsrcprops),
5078 unif.c, unif.h (scm_raprin1, rapr1),
5079 variable.c (prin_var): Changed argument `int writing' to
5080 `scm_print_state *pstate'.
5082 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5083 that it will be called before scm_init_print.
5085 * print.c (scm_prin1): Print states are now allocated when calling
5086 scm_prin1 and then passed around to all printing functions as an
5087 argument. A cache `print_state_pool' enables reuse of print
5089 (scm_make_print_state): New function.
5090 (scm_iprin1): Adaption to print states.
5091 (scm_iprlist): An initial "hare and tortoise" scan brings down
5092 time complexity to O (depth * N). (Better time complexity will be
5093 achieved when the printing code is completely rewritten.)
5095 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5097 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5098 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5099 it gets done whether or not the cache variable has a value.
5101 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5103 Distinguish #f and ().
5104 * __scm.h: #undef SICP.
5105 * pairs.h (SCM_EOL): Delete this definition, equating it with
5107 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5108 the value it used to have. Doc fixes, too.
5110 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5112 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5113 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5114 Lord's implementation of structs, allowing for tail arrays as
5115 described in the manual. Also fixed some bugs. (Both the interface
5116 and the implementation should be improved.)
5118 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5120 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5121 People who whish to see the source can do `(print-enable 'source)'.
5122 Removed #ifdef DEBUG_EXTENSIONS.
5124 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5126 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5127 integer (assuming for now accepting an integer is a good thing).
5129 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5130 %S will be used instead for write'ing arguments.
5132 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5133 asserts. fix a few other asserts.
5134 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5135 scm_uniform_vector_ref, scm_array_set_x,
5136 scm_dimensions_to_unform_array): change args in
5137 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5138 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5139 scm_substring_fill_x): likewise.
5140 gsubr.c (scm_gsubr_apply): likewise.
5141 eval.c (SCM_APPLY): likewise.
5143 * eval.c (4 places): replace scm_everr with lgh_error or
5146 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5147 scm_memory_error): new procedures.
5148 scm_everr: deleted. can use scm_wta, dropping first two args.
5149 scm_error: convert NULL subr to SCM_BOOL_F.
5151 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5154 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5157 * error.c, error.h: new error keys: scm_arg_type_key,
5158 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5160 scm_wta: reimplement using lgh_error instead of scm_everr.
5162 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5164 * gdbint.c: scm_lread now has one more argument.
5166 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5167 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5168 loading source from non-file ports, which, e. g., happens when
5169 using the Emacs interface).
5171 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5174 * read.c: Added code for recording of positions of source code
5175 expressions; New functions: recsexpr, scm_lreadrecparen;
5176 _scm_make_srcprops --> scm_make_srcprops
5177 (scm_flush_ws): Removed updating of positions counters. This work
5178 is already done by scm_gen_getc
5180 * read.h: Added prototype for scm_lreadrecparen
5182 * print.c: Added #include "alist.h"
5184 * eval.c: Added #include "hash.h"
5186 * eq.c: Added #include "ramap.h"
5188 * options.c: Documentation fixes.
5190 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5191 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5192 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5193 --> scm_make_srcprops
5195 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5196 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5197 function calls in the definition of the whash access macros.
5199 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5201 * init.c (scm_boot_guile): Add level of indirection to
5202 scm_boot_guile_1() to ensure that stack base pointer is properly
5203 initialized. There was no guarantee that variable i was the
5204 highest/lowest variable on stack (i.e. the call frame of
5205 scm_boot_guile was not completely protected from gc).
5207 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5209 * ports.h (scm_port_table): put back file_name, it will be used to
5210 support debugging. Undo related changes in fports.c, ioext.c,
5213 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5215 * ports.h (scm_port_table): remove file_name member for now, it seems
5217 * fports.c (scm_open_file): don't set file_name in PTAB.
5218 (prinfport): don't use file_name in PTAB.
5219 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5220 * ports.c (scm_add_to_port_table): don't intialize file_name.
5221 (scm_port_file_name): remove for now.
5222 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5224 * fports.h (scm_mkfile): prototype deleted.
5225 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5227 * debug.c, unif.c: use scm_out_of_range instead of
5228 wta for range errors (ASSERT still needs work).
5230 * error.c, error.h (scm_out_of_range): new procedure.
5232 * error.c, error.h (scm_out_of_range_key): new key.
5234 * posix.c (scm_sync): #else was missing.
5236 * error.c, error.h: append _key to names scm_num_overflow and
5239 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5240 of consing an empty list.
5241 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5242 of macros, saves code and string space.
5243 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5244 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5245 lower case. Rename scm_syserror_m to scm_syserror_msg.
5246 error.h: prototypes for new procedures.
5248 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5250 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5252 * error.c, error.h: setup scm_num_overflow key.
5254 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5255 Remove definition of SCM_OVSCM_FLOW.
5257 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5259 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5260 explicit message and args.
5262 * error.c, error.h, __scm.h: change system_error_sym to
5265 * error.c (system_error_sym): remove leading %% from the Scheme name
5268 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5270 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5272 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5273 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5274 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5275 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5276 renamed. (These were introduced by unsupervised name
5279 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5281 * print.c: Added code for detection of circular references during
5282 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5283 a hook for printing of closures (accessible via print options).
5284 This leads to a split of calls to scm_iprin1 into two classes:
5285 elementary print operations (e. g. the code which prints a smob)
5286 still use scm_iprin1 while top level calls (like scm_display) use
5287 scm_prin1. scm_prin1 begins by clearing the data structure used
5288 to record reference information.
5290 * print.h: Added declarations of scm_prin1 and scm_prlist.
5292 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5294 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5296 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5298 * error.c (err_head): scm_iprin1 --> scm_prin1
5300 * debug.c: Adjusted header comment.
5304 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5306 * strerror.c: Doc fix.
5308 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5310 * gdbint.c (gdb_read): Now possible to run during GC.
5311 (unmark_port, remark_port): New functions.
5313 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5315 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5316 of allocating a new string object. Also, increase size by
5317 the factor 2 instead of 1.5.
5319 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5321 * __scm.h (SCM_P): Corrected to run under traditional C.
5323 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5326 * async.c: Calls to scm_sysintern corrected.
5328 * async.h (scm_async_clock): Redundant declaration removed.
5330 * continuations.c (scm_dynthrow): Redundant declaration removed.
5332 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5333 Definition typos corrected.
5335 * debug.h: Missing declarations of functions in debug.c added
5338 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5339 Missing declarations to functions in eval.c added.
5341 * filesys.c: Possibly uninitialized variable rv.
5343 * gc.h (scm_object_addr, scm_unhash_name): Missing
5344 declarations of functions defined in gc.c added.
5346 * genio.c: Possible typos str_data -> wstr_data. ???
5348 * genio.c: Possibly unintended shadowing of local variable
5349 `int c' (gotos out of scope of inner `c'). ???
5351 * init.c: Uninitialized `SCM last' may be used.
5353 * ioext.h: (scm_sys_isatty_p): Typo.
5355 * list.h (scm_list_head): Missing prototype for function in
5358 * numbers.c (scm_two_doubles): Changed from extern to static
5359 (is used only within numbers.c).
5361 * numbers.h: Repeated declarations removed.
5363 * ports.h (scm_close_all_ports_except): Declaration for the
5364 function defined in ports.c added.
5366 * posix.h: Missing declarations added.
5368 * procs.h (scm_make_subr_opt): Missing declaration added.
5370 * socket.h (scm_sys_gethost): Missing declaration added.
5372 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5374 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5375 Missing declarations added.
5377 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5379 * struct.c: Uninitialized variable `SCM answer' may be used.
5381 * unif.c (l2ra): Declaration prototype.
5383 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5384 defined in ramap.c).
5386 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5387 Redundant declarations removed (they are in ramap.h).
5389 * variable.h (scm_make_udvariable,
5390 scm_make_undefined_variable): Declaration corrected to
5391 correspond variable.c.
5393 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5394 Missing declarations added.
5396 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5398 * Makefile.in (distclean): Don't forget to delete fd.h.
5400 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5402 * fd.h.in, tags.h: Trivial cleanups.
5404 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5405 marksweep.h just declared functions from gc.c.
5406 * gc.h, libguile.h: Don't #include "marksweep.h".
5407 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5408 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5409 dependencies updated.
5411 * libguile.h: Don't #include "files.h"; it's been deleted.
5413 * files.c (scm_sys_delete_file): Moved to filesys.c.
5414 File is now empty; deleted.
5416 * filesys.c: scm_sys_delete_file is now here. Remove
5417 #if's; they seem to rely on remnants of an old portability
5418 regimen. If the problems come up again, solve them properly,
5419 using autoconf. Specifically: Don't test M_SYSV, and #define
5420 remove to be unlink if it's #defined; don't use remove just
5421 because HAVE_STDC_HEADERS is #defined.
5422 * filesys.h: Add declarations for scm_sys_delete_file.
5423 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5424 files.o, files.h, files.c, and files.x.
5425 * init.c: Don't #include "files.h", and don't call scm_init_files.
5427 Use SCM_P instead of PROTO; the latter intrudes on the user's
5429 * params.h: Deleted; definition of SCM_P moved to...
5430 * __scm.h: ... here, where it replaces PROTO macro.
5431 * libguile.h, smob.h: Don't #include "params.h".
5432 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5433 smob.h: Fix prototypes accordingly.
5434 * Makefile.in: Update dependencies.
5435 (inner_h_files): Remove params.h.
5437 * gc.c: #include "gc.h"; every module should include its header,
5438 to let the compiler cross-check the declarations against the
5441 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5442 simpos.h: #include "libguile/__scm.h".
5444 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5446 * init.c: Don't forget to #include smob.h and init.h.
5447 * Makefile.in: Dependencies updated.
5449 * smob.h: Use PROTO instead of #if __STDC__.
5451 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5453 * __scm.h: Doc fixes.
5455 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5456 <angles>; this allows `make depends' to work properly.
5458 * libguile.h: #include smob.h and pairs.h before the others; they
5459 define typedefs used by other headers.
5461 C files should #include only the header files they need, not
5462 libguile.h (which #includes all the header files); the pointless
5463 recompilation was wasting my time.
5464 * Makefile.in (all .o dependency lists): Regenerated.
5465 * libguile.h: Don't try to get a definition for size_t here...
5466 * __scm.h: Do it here.
5467 * _scm.h: Since this is the internal libguile header, put things
5468 here that all (or a majority) of the libguile files will want.
5469 Don't #include <libguile.h> here; that generates dependencies on
5470 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5471 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5472 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5568 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5569 * weaks.c: Get "weaks.h".
5571 * stackchk.h: #include "libguile/debug.h",
5573 * print.h, read.h: #include "options.h", since everyone who uses
5574 either of these files will need that.
5576 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5577 anyone who uses this file will need them to define the smob
5578 printing functions. Also, get markers.h, since people will need
5579 to #define the mark functions.
5581 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5582 * ports.h: ... to here.
5584 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5585 don't rely on archaic C default type rules.
5587 * fports.h: #include "libguile/ports.h", since you need that in
5588 order to parse this.
5590 * genio.h: #include "libguile/print.h", because you need that to
5591 parse this; don't bother #including "ports.h", since print.h gets
5594 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5596 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5597 this; it's now a reference to an element of *scm_root.
5599 * debug.h: Don't #include "options.h"; the compiler won't be able
5600 to find that once the headers are installed; instead, #include
5601 "libguile/options.h".
5602 * gc.h: Same, with marksweep.h.
5603 * mbstrings.h: Same, with symbols.h.
5604 * scmhob.h: Same, with _scm.h.
5605 * smob.h: Same, with params.h.
5607 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5608 C files; there's no need for this, and it forces recompilations
5611 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5613 * error.c (scm_error): declare scm_error_callback.
5615 * error.h: prototype for scm_error_callback.
5617 * __scm.h: define lgh_error.
5618 (SCM_SYSERROR): redefine using lgh_error.
5620 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5622 * error.c (scm_error): new procedure.
5624 * error.h: prototype for scm_error.
5626 * Makefile.in (install): install scmconfig.h from the current
5627 directory, not $(srcdir).
5629 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5631 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5632 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5633 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5634 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5635 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

5638 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5639 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5640 vports.h, weaks.h: #include "libguile/__scm.h", not
5641 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5642 dependencies are within libguile properly.
5644 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5646 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5647 when scmconfig.h doesn't exist.
5649 * load.c (scm_sys_try_load): Correct spelling.
5651 * feature.c (scm_loc_features): Make this static.
5653 * Makefile.in (libpath.h): Omit trailing slash from path. We
5654 shouldn't require it of users, so why put it here?
5656 Move code to initialize and search %load-path from ice-9 to C
5657 code, so we can use the load-path to find the ice-9 boot code;
5658 this makes it easier to run Guile without installing it. See
5659 corresponding changes in guile/Makefile.in.
5660 * feature.c: Move stuff concerned with the load path to load.c.
5661 (scm_compiled_library_path): Deleted.
5662 Don't #include libpath.h here.
5663 * feature.h: Don't mention scm_compiled_library_path.
5664 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5665 <sys/stat.h>, and <unistd.h> (if present).
5666 (R_OK): #define if the system hasn't deigned to.
5667 (scm_loc_load_path): New variable.
5668 (scm_init_load_path, scm_sys_search_load_path,
5669 scm_sys_try_load_path): New functions.
5670 (scm_init_load): Initialize scm_loc_load_path to point to the
5671 value cell of the Scheme %load-path variable.
5672 * load.h: Add declarations for scm_sys_search_load_path,
5673 scm_sys_try_load_path.
5674 * init.c: Call scm_init_load_path.
5675 * Makefile.in (feature.o, load.o): Dependencies updated.
5677 * load.c, load.h: Rewrite using PROTO macro.
5679 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5681 * gc.c (scm_cellp): New function: C predicate to determine if an
5682 SCM value can be regarded as a pointer to a cell on the heap.
5684 * gc.h: Added declaration of scm_cellp.
5686 * gdb_interface.h: New file: The GDB interface header from the GDB
5689 * gdbint.c: New file: GDB interface.
5691 * gdbint.h: New file: GDB interface.
5693 * libguile.h: Added #include <libguile/gdbint.h>.
5695 * init.c (scm_boot_guile): Added scm_init_gdbint.
5697 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5698 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5699 found if object files and source are kept separate).
5701 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5703 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5705 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5707 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5708 TK_SRC_DIR; they're not relevant any more.
5710 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5711 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5713 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5715 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5716 search path, so we can find the <libguile/MUMBLE.h> headers.
5718 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5720 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5721 implicit in the .c.o rule.
5722 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5725 Put the library path in a header file, instead of passing it on
5726 the command line in every compilation.
5727 * Makefile.in (libpath.h): New target.
5728 (feature.o): Depend on libpath.h.
5729 (clean): Delete libpath.h.
5730 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5731 * feature.c: ... #include "libpath.h" here.
5732 * .cvsignore: Ignore libpath.h.
5734 Don't install the unwashed masses of Guile header files in the
5735 main #include path; put most of them in a subdirectory called
5736 'libguile'. This avoids naming conflicts between Guile header
5737 files and system header files (of which there were a few).
5738 * Makefile.in (pkgincludedir): Deleted.
5739 (innerincludedir): New variable; this and $(includedir) are enough.
5740 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5741 (installed_h_files): Divide this up. Now this variable lists
5742 those header files which should go into $(includedir) (i.e. appear
5743 directly in the #include path), and ...
5744 (inner_h_files): ... this new variable says which files appear in
5745 a subdirectory, and are referred to as <libguile/mumble.h>.
5746 (h_files): List them both.
5747 (install): Create innerincludedir, not pkgincludedir. Put
5748 the installed_h_files and inner_h_files in their proper places.
5749 (uninstall): Corresponding changes.
5750 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5751 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5752 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5753 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5754 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5755 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5756 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5757 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5758 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5759 vports.h, weaks.h: Find __scm.h in its new location.
5760 * __scm.h: Find scmconfig.h and tags.h in their new locations
5761 (they're both "inner" files).
5763 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5765 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5767 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5769 * posix.c: Doc fixes.
5771 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5773 * socket.c: Don't include a prototype for inet_aton; just use a
5774 K&R style declaration, to avoid warnings but minimize the chance
5775 of conflicts with the system.
5777 On NextStep, <utime.h> doesn't define struct utime, unless we
5778 #define _POSIX_SOURCE before #including it.
5779 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5780 * acconfig.h: New comment text for above CPP symbol.
5781 * configure.in: Call it.
5782 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5784 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5786 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5787 testing for __EMX__.
5789 * posix.c: #include <libc.h>, if it exists.
5791 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5792 don't even know if the latter exists.
5794 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5795 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5796 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5798 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5800 (scm_init_posix): Use them when initializing the Scheme constants
5803 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5805 * Makefile.in (libdir, includedir, bindir): Use the
5806 autoconf-supplied values, instead of deriving them ourselves.
5807 (pkgincludedir, datadir, pkgdatadir): New variables.
5808 (install, uninstall): Put the header files in a special
5809 subdirectory, not in the main search path.
5811 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5812 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5814 * Makefile.in (IMPLPATH): Deleted; never used.
5816 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5817 on the Tcl/Tk source any more.
5818 (INCLUDE_CFLAGS): Remove references to the above.
5820 * Makefile.in (version.o): Corrected dependencies.
5822 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5824 * libguile.h: #include "version.h"
5826 * init.c (scm_boot_guile): Call scm_init_version.
5827 * gscm.c (gscm_run_scm): Call scm_init_version.
5829 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5830 GUILE_VERSION): AC_DEFINE these.
5831 (acconfig.h): #undef the above symbols.
5833 * Makefile.in (libobjs): Add version.o.
5834 (installed_h_files): Add version.h.
5835 (c_files): Add version.c.
5836 (gen_c_files): Add version.x.
5837 (version.o): New rule.
5838 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5839 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5840 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5841 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5842 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5843 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5844 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5845 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5846 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5847 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5848 weaks.o): Add version.h to dependency lists.
5849 (markers.o): Remove duplicate rule.
5851 * version.h: New file.
5853 * version.c: New file.
5855 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5857 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5858 array; use it appropriately. Since GCC is quite happy to
5859 subscript functions, it never warned us about this; we should use
5860 -Wpointer-arith in the future. I guess we never tested
5863 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5865 * socket.c: Doc and copyright fixes.
5867 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5869 * debug.c: Fixed and improved gdb support.
5871 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5873 * socket.c: Added declaration of inet_aton to avoid compiler
5874 warning. (Hope this solution is correct.)
5876 * stime.c: Added declaration of ftime. (This is missing in
5879 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5881 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5883 * Makefile.in (c_files): add strerror.c.
5885 * strerror.c: new file from Emacs' sysdep.c.
5886 maybe configure should also check for sys_errlist.
5888 * configure.in (AC_REPLACE_FUNCS): add strerror.
5890 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5892 * debug.c (scm_init_debug): Added initialization for
5893 scm_evaluator_traps.
5895 * debug.h, debug.c: Various name changes.
5896 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5897 "debug-options-interface". See commentary in options.c.
5899 * options.h, options.c: Options now have documentation strings.
5900 Also added a long explanatory commentary.
5902 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5905 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5906 last_debug_info_frame is now updated in all cases.
5908 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5911 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5913 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5914 Added option STACK_CHECKING.
5916 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5918 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5920 * __scm.h: Removed symbols for debugging support.
5922 * acconfig.h: Added symbols for debugging support.
5924 * configure.in: Added user option for debugging support.
5925 --enable-debug will include the debugging code into libguile.a.
5927 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5928 scm_relocate_chunk_to_heap.
5930 * debug.c: New file: low-level debugging support. It also
5931 includes support for debugging with gdb. (The extensions to gdb
5932 are written by Per Bothner at Cygnus.)
5934 * debug.h: New file: low-level debugging support.
5936 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5937 argument pairs. Extensive modifications to the debugging
5938 evaluator. Added "SECTION:" commentaries to clarify what happens
5939 when, during double compilation. Renamed EVALIMP --> EVALIM.
5940 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5941 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5942 the beginning of the file. New procedure: scm_unmemocopy.
5943 Added some global state variables needed by the debugging
5944 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5945 check_entry, check_apply, check_exit, debug_options and
5946 evaluator_traps. New acro: undefine.
5948 * eval.h: Renamed EVAL --> XEVAL.
5950 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5951 --> scm_make_weak_key_hash_table.
5953 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5954 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5956 * libguile.h: Conditionally include debug.h
5958 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5959 scm_object_properties shouldn't return handle. `handle' now gets
5960 initialized in scm_set_object_properties_x. scm_object_properties
5961 doesn't any longer create an entry in scm_object_whash.
5963 * options.c: New file: handling of run time options.
5965 * options.h: New file: handling of run time options.
5967 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5969 * print.c: New procedure: scm_print_options
5971 * print.h: Defines for print options.
5973 * read.c: New procedure: scm_read_options
5975 * read.h: Defines for reader options.
5977 * root.h: Added scm_source_whash among scm_sys_protects.
5979 * srcprop.c: New file: source properties.
5981 * srcprop.h: New file: source properties.
5983 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5984 (Bug found by A. Green.)
5986 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5988 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5990 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5992 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5994 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5995 and should be called by the final client.
5997 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5999 * gc.h: Use the PROTO macro when declaring functions.
6000 * gc.c: Use the PROTO macro when declaring static functions.
6001 Remove the CPP hair around function definitions.
6003 * gc.c (scm_init_storage): Initialize scm_asyncs.
6005 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6006 preprocessor symbol; "__scm.h" is where it might get #defined.
6007 * __scm.h: Similar: #include <scmconfig.h> before testing
6010 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6012 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6014 * init.c (scm_boot_guile): Add init_func argument; call
6015 (*init_func) instead of calling scm_appinit; it's ucky to
6016 hard-code names for the user's procedures.
6017 * init.h (scm_boot_guile): Adjust declaration.
6019 * __scm.h (PROTO): New macro, for declaring functions with
6022 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6023 eliminate all the __STDC__ conditionals.
6024 (scm_boot_guile): Add declaration.
6025 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6026 Remove __STDC__ conditionals around function definitions; the
6027 declarations in init.h will provide the same information, more
6030 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6031 complain about it in the error message; the error message is
6032 adequate without that note, and there's nothing the user can do
6035 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6037 * Makefile.in (ancillary): Drop def.sed.
6039 * posix.c (scm_init_posix): Use numeric values, rather than
6040 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6041 F_OK. The symbols aren't available on some systems, and I'm
6042 pretty sure their values are fixed by common widespread practice.
6043 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6045 More functions unavailable on some systems.
6046 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6047 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6049 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6050 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6051 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6052 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6053 stub that signals an error as the #else.
6055 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6057 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6059 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6061 * unif.c: include ramap.h.
6063 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6065 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6067 * ports.c: include sys/ioctl.h.
6069 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6071 * configure.in: check for sys/ioctl.h.
6073 * ports.c: include <malloc.h> not "malloc.h".
6075 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6077 * fports.c: remove ttyname and tmpnam declarations.
6079 * posix.c: fewer ttyname declarations.
6081 * fports.c: include <string.h> not "string.h".
6083 * init.c, ioext.c: include string.h and unistd.h.
6085 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6087 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6088 genio.c, simpos.c, vports.c: include string.h.
6090 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6092 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6094 (scm_addr_buffer_size): change type from scm_sizet to int.
6095 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6096 from scm_sizet to int.
6098 * error.c: include unistd.h.
6100 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6103 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6105 * __scm.hd, def.sed: deleted.
6107 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6109 Changes for NeXT, suggested by Robert Brown.
6110 * configure.in: Call AC_TYPE_MODE_T.
6111 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6112 NeXT. Put header file list in alphabetical order.
6113 * configure, scmconfig.h.in: Regenerated.
6114 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6116 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6119 * acconfig.h: New file, providing documentation for the CPP
6120 symbols defined in configure.in
6121 * acconfig-1.5.h: Removed; superceded by the above.
6123 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6125 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6127 * fports.c (scm_open_file): don't return #f, throw error.
6129 * ioext.c (fileno): renamed from %fileno.
6130 (soft-fileno): deleted.
6132 * ports.c (scm_port_revealed): don't need to check for -1 from
6134 (scm_set_port_revealed_x): return unspecified, not #f.
6136 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6138 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6140 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6142 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6144 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6146 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6147 This is necessary on Ultrix, and doesn't hurt portability.
6149 * Makefile.in (dist-dir): New target, implementing a new dist system.
6150 (installed_h_files): Put in alphabetical order.
6151 Remove duplicate entries for markers.h and unif.h.
6152 (c_files): Remove duplicate entries for markers.c.
6153 (ancillary): Renamed from anillery; all uses changed. Remove
6154 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6155 Remove all the ../doc/* files; doc/Makefile.in handles that.
6157 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6159 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6160 every if must have an else, or else the whole command has a
6161 non-zero exit code whenever the if's condition is false.
6163 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6165 * posix.c: include string.h.
6167 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6169 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6172 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6173 Remove leading % from scheme names.
6174 Do not return error values, call SCM_SYSERROR or similar.
6176 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6178 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6180 * struct.c (scm_init_struct): new file.
6182 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6184 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6185 (scm_list_head): added list-head for rapidly chopping argument
6186 lists off of longer lists (and similar).
6188 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6190 * objprop.c (scm_object_property): assq the cdr of the whash
6191 handle for obj, not the handle itself.
6193 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6195 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6196 weak hash tables last of all marking to avoid an obscure gc bug.
6197 WARNING: circular lists stored in a weak hash table will hose us.
6199 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6201 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6202 new functions similar to scm_substring_move_left_x and
6203 scm_substring_move_right_x.
6205 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6207 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6210 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6212 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6214 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6216 * strports.c (scm_strprint_obj): convenience function. C for
6217 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6219 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6220 removed to a separate library
6222 * init.c (scm_boot_guile): copied from guile-tcl.c.
6223 Initialization specific to tcl interpreters removed.
6225 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6227 * ports.c (scm_ports_prehistory): size malloced here doesn't
6228 matter so long as it is non-0 (got rid of "* 4").
6230 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6232 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6233 since its definition was bogus).
6235 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6237 * mallocs.[ch]: back again (for rx at least).
6239 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6241 * ports.c: removed functions relating to the mapping between ports
6242 and descriptors. (That stuff is unix-specific and should be collected
6243 in a separate library).
6245 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6246 (Tom Mckay@avanticorp.com)
6248 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6250 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6251 handled correctly (SCM_FREEP was applied to them) -- test for
6252 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6420 initialization to fix a race condition.
6422 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
